FASTEST Rubber Chicken Bone Experiment

If you soak chicken bones in vinegar, the vinegar will react with the calcium in the bones and weaken them so that they will become soft and rubbery, as if they had come from a rubber chicken. Vinegar is a mild acid, which breaks down calcium. CLR just does it a lot faster.   It is the calcium in your bones that makes them hard and strong. As you age, you may deplete the calcium faster than you replace it. If too much calcium is lost from your bones, they may become brittle and susceptible to breaking.   Exercising and…

Straw Wrapper Wiggle

When drop water on the wrapper, the water molecules will try to get as close as it can to the surface of the paper. And since water molecules are also attracted to one another, it will drag its friends along. This is called capillary action and is why the water travels along the wrapper. The wrapper wiggles and stretches out as the water moves because as its fibers absorb water they swell and straighten out.  

Water to Cranberry juice Experiment

Start off with ….Out of sight of your audience, add about one teaspoon of sodium carbonate powder (Washing Soda) which is Baking Soda that you preheat to 400 degrees (204 c). Then pour in 16oz (pint) of water in a pitcher and mix until solution appears clear. This will be the “plain water”. With two clean cups, add about 10 drops of phenolphthalein solution (pH indicator) to the bottom of one glass. This will become the “Cranberry juice” glass.   Now In front of your audience, pour some of the “plain water” into the empty cup. Next, say some magic…

Steam Powered Vacuum Experiment

Fill a glass bottle with enough water so when its on its side it won’t spill out. Then microwave for a 1:30 on high. The bottle is going to be VERY HOT! Use caution and use hot pads. Make sure to wear safety glasses!   Already with a bowl of water on the table, pour the water out of the bottle into the bowl, then put the tip of the bottle into the bowl of water straight up. Hold on tight as the vacuum has a huge amount of force.   When we microwave the bottle and water it becomes…

Pick up a Ice cube with a string and salt experiment

When salt is sprinkled over ice it melts. However, when it is used in such a small amount, like in our experiment, the water around the ice freezes again quickly, as salt lowers the freezing point of water to below O degrees.   This means that the string gets trapped as the water around it refreezes, making it stick to the ice.   A great example of how road crews use salt is they put salt on the roads in the winter to prevent roads from getting icy. The salt lowers the melting point of ice and stops roads from…

Boiling Water with Ice Experiment

Icing the part of the bottle with air in it slightly lowers the pressure, because the air molecules rattle around less when they’re colder. Thats what causes a little bit of water to boil, until the pressure builds back up.   There’s a much more important effect. The bottle mostly has water vapor, not air, up in the top part of the bottle. Icing it cools it enough so that there the vapor condenses back from a gas to a liquid. That lowers the pressure a lot, causing more boiling. So with the main part of the bottle is very…

Pepsi (Coke) and Milk Experiment

The reaction of phosphoric acid to proteins in the milk – they are cut and causes a substance to be deposited in solid form from a solution.   It is a reaction of the Phosphoric Acid contained in the soft drink to the milk. Phosphoric Acid molecules attach to the milk giving them more density and separate out while the remaining liquid that makes up the milk and soft drink now being lighter floats on top. The solid matter is basically milk that has been curdled by the addition of the more acidic soda.   Both items are acidic but…

How to Stop a Soda Can from Exploding Experiment

Shaking an unopened can of soda causes bubbles of carbon dioxide gas (CO2) to cover the inside walls of the can. At some point we all have had or seen someone with a can that exploded as it was opened.   When you open a shaken can, the pressure in the liquid drops quickly and all the bubbles or so dioxide gas bubbles increases instantly. And it shoots out everywhere! The quickly expanding bubbles force any liquid above them out of the can as a foaming mess.   The myth is tapping the top of the can before opening it…

Freeze water in one second experiment

Everyone knows that water freezes at 32 degrees (0 °C) – or does it? When water freezes, it needs a nucleus in order for the solid crystals to form and become ice. Water is typically full of particles and impurities which have no problem kicking off the crystallization process. However, purified water by definition doesn’t have those impurities. With nothing for the water molecules to latch onto, purified water can be supercooled as far as -40°C.   The energy generated from firm hit on the side of the bottle forces the supercooled water molecules to form a crystal in a…

Self Moving Toothpick Experiment

Toothpicks are made of dry wood. When I broke them in the middle, the wood fragments inside compress. Once we add water to the center circle of the star, capillary action causes the water to be absorbed into the toothpicks.   The water moves inside the dry toothpick from the starting point of the crack and continues along the length to the pointed tips. The capillary action or water traveling inside the toothpick causes the toothpicks to straighten out. The set up with 10 points creates a 5 point star.  

Harry Potter Butter beer Recipe

Trivia question answer below in comments: Does anyone know how much Butter beer cost at the Hog’s Head?   “Why don’t we go and have a butterbeer in the Three Broomsticks, it’s a bit cold, isn’t it?” – Hermione Granger inviting Harry   Butterbeer at The Wizarding World of Harry Potter could be served either cold with a taste similar to cream soda or frozen as a slush with a butterscotch-like foam on top (My favorite). One may also purchase it either in a regular plastic cup or in a collectible mug. As of 12 December, 2012, over five million…

Red Cabbage Juice: A Homemade pH Indicator Experiment

Red cabbage contains a pigment molecule called flavin (an anthocyanin). This water-soluble pigment is also found in apple skin, plums, poppies, cornflowers, and grapes.   Red cabbage juice contains a natural pH indicator that changes colors according to the a acidity of the solution. This is very easy to make and exhibits a wide range of colors.   You can make it a couple different ways, one by chopping up the red cabbage into strips adding 2 cups of hot water and then blending it and then pouring into a coffee filter. This is give you a dark purple indicator…

Wave in a bottle Experiment – Activity

Now move the bottle back and forth, side to side and you will notice you have a wave in the bottle!   The waves will be bigger at one end of the bottle and smaller at the other.   The reason is because Your bottle wave is like an ocean wave. Water moves up and down and doesn’t go forward as the wave goes through the water.   The friction between water and wind makes a wave. Longer waves travel faster than shorter ones and go further before friction makes them disappear.   Our planet waves also happen when our…

Kaye effect Experiment

The Kaye effect occurs when a thin stream of shampoo is poured onto a surface. Though most of the time it just clusters in a pile, the surprising effect occasionally fires off an arcing streamer! The phenomenon ends when the ‘dancing’ jet hits the primary jet and suddenly collapses.   These streamers of fluid can actually fly quite far — the ones in my initial experiment were traveling up to 8 inches, leaving the bowl entirely and almost hit my camera. This is named after its first observer A. Kaye, who could offer no explanation for this behavior.   So…

TORNADO in a jar experiment

Remember to just add a small amount of dish soap or it might get to cloudy.   The swirling motion you give the jar forms a vortex and is a easy way to create your own tornado. You can add food coloring or glitter to add some awesome tornados.   Tornado alley is region in the Central United States where tornadoes often occur. The states of Texas, Oklahoma, Nebraska, Kansas, Iowa and Missouri are in Tornado Alley.   The Fujita Scale In 1971 Dr T. Theodore Fujita developed a scale to classify a tornado’s speed and potential for damage. Tornadoes…

Refraction of Light with a arrow experiment

A pencil is placed with a diagonal orientation within a 2/3-filled glass of water. At the surface of the water, the pencil appears to be misaligned or broken; the portion of the pencil above the water is shifted relative to the image viewed under the water. The bending of the path of light as it passes from the water to air causes the observed distortion of the image of the pencil.   Next, I poured water into a glass and placed an arrow on a piece of paper about 4 to 5 inches (10-12 cm) behind the glass of water….

Why sunsets are Red & Yellow? Experiment

Milk is a colloid, which contains tiny particles of fat and protein. Mixed with water, the particles scatter light much as dust scatters light in the atmosphere. Light is scattered differently, depending on its color or wavelength. Blue light is scattered the most, while orange and red light are scattered the least.   Light travels in a straight line until it encounters particles, which deflect or scatter it. In pure air or water, you can’t see a beam of light and it travels along a straight path. When there are particles in the air or water, like dust or ash…

Putting on a swim cap without pulling or snagging hair is a challenge.   Suggestions stretch it wide, Get your hair wet Have a friend help Try a different cap   Well I heard you could put on a swimming cap by having someone drop it on your head full of water would work. So I had my 2 nieces come help me out. Some how I was voted in as…

The Drip Temperature experiment!

Which runs faster: hot or cold water? Hot runs faster because you can’t catch a hot, but you can catch a cold. What Happens: The pin holes on the bottom of each cup are the same size, you’ll see that the hot water drips faster then the cold water. If the cold water is cold enough it may even stop, like it did in this demo. The cold actually stop dripping for a couple seconds.   Why: Molecules exist although we can’t see them. The molecules in hot water move faster then in cold water. The faster the move, the…

Bernoulli’s principle Ball in stream of water experiment

A mathematician called Bernoulli found that areas where fast moving fluids are present have a lower pressure than the surrounding environment. Furthermore, he found that water running over a curved surface of also exhibits the same low pressure, the faster the water the lower the pressure.   So, why did the ball move toward the water stream? Fluids (and air) want to move from high pressure areas into low pressure areas. You created a situation where the wet side of the ball had lower pressure compared to the dry side of the ball. The high air pressure on the dry…
