Tea Bag Rocket

This cool experiment is a fun after dinner experiment with the family. Your guest won’t believe their eyes as the Rocket shoots to the ceiling.   Steps 1) Take your tea bag out of its container, and look for a small staple that connects the paper and string to the actual bag. 2) Carefully pull back the staple and remove it from the bag. 3) Unfold the tea bag and empty out the tea leaves. 4) Put your finger in the middle of the cylinder. 5) Place the cylindrical tea bag upright on a non-flammable surface such as a plate….

Fire Tornado Experiment

When I start to spin the garbage can the center the fire created the perfect fire tornado. It all starts with the heat from the flame that causes the surrounding molecules of air to rise. Couple this with the rotational motion of the screen and you have the perfect storm, so to speak. The rotating screen gives the air molecules an initial spin (called angular momentum). The vertically rising hot air molecules collide with the rotating screen, and the angular momentum of the screen is transferred to the rapidly rising air molecules, giving them a “twist.” Fresh air fuels the…

Steel wool and 9 volt battery Experiment

Here is a great how-to science experiment that you can try at home: burning fine steel wool with only a battery. The reaction from your friends will have them speechless and the visuals is enough to get anyone excited.   Steps 1) Pull the steel wool apart into thin strips. 2) Place the steel wool in the baking pan with aluminum foil. 3) Touch the ends of the battery to the steel wool.   We used a 9-volt battery to light the steel wool because the terminals are close together. Touching the battery to steel wool sends a current through…

Raising Matchstick Experiment

How it works? The reason we light it in the middle, is most of the weight of the match is burned up by the flame before it lights the highly flammable match heads.   Since the match heads are leaning together they ignite at the same time under very high intense heat.   This high heat then fuses the match heads together. As the flame continues to burn the propped up match, it starts to curl up and you can remove the coin.   Because of the weight of the match being burnt, the fusing of the match heads with…

Pinwheel Spiral Spinner Experiment

Spiral Spinner – Hot air moves moves faster. Because the molecules now have the energy to move around more, they do and as they do they spread out and the gas becomes less dense. This lighter gas now rises up away from the heat source.   If a pinwheel is free to move and constructed correctly, the rising heat can now make it turn. The heat rises relatively straight up so to get the pinwheel to turn the blades need to be orientated in a way that causes the moving air to push them. As the hot air continues to…

Smoke Waterfall Experiment

Take your sticky note and roll it up with the sticky part facing up. Start rolling opposite side of the sticky part. You want to be able to make it small enough to fit into your L bracket. Then place paper in L bracket at a 45-degree angle.   You need a room with still air as possible. I use the inside of a glass or a fish tank. This will allow so moving air in the room will not touch the waterfall. Now light the sticky note.   Now the waterfall should do its thing.   You are probably…

Extinguish Fire with Carbon Dioxide experiment

HOW THE CANDLE EXPERIMENT WORKS When you mix baking soda and vinegar together, you produce carbon dioxide. The carbon dioxide is heavier than air, so it will sit in the bottom of the glass. When you pour the gas from glass onto the candle, you are pouring out the carbon dioxide, which will sink and displace the (oxygen-containing) air surrounding the candle with carbon dioxide.   HOW BLOWING OUT A CANDLE WORKS When you blow out a candle, your breath contains more carbon dioxide than it did when you inhaled the air, but there’s still oxygen that can support wax…

Orange Candle Experiment

There are two parts that work together in a candle: the fuel, made of some sort of wax, and the wick, made of some sort of absorbent twine. In the case of our orange, the olive oil is the wax and the wick is the central column, which supports the walls between each segment.   When you light a candle, you melt the wax in and near the wick. The wick absorbs the liquid wax and pulls it upward. The heat of the flame vaporizes the wax, and it is the wax-vapor that burns. The reason the wick does not…

Do White Candles Burn Faster then Color Candles?

Ends up color candles burn faster for me. Test it for yourself and let me know what results are?   Have you ever wondered, do white candles burn faster than colored candles? It seems that just about every element of a candle can affect how fast they burn, so it’s no wonder that people are curious about the addition of candle dyes and colors.   Theory Most people seem to think that plain white candles will burn faster than those with added dyes. The reasoning behind this theory is that the plain wax is more pure, and will give a…

Rocking Candle Experiment

Safety: Make sure you have adult supervision as you will be lighting both ends of the candle.   This experiment teaches how combustion and Newton’s Third Law of Motion. A candle, balanced between a pair of glasses, rocks or up and down on its own.   Carve the bottom part of the candle so the wick is showing. Make sure that the bottom end had more wax than the top. Then make a hole in the candle half way in the middle. The hole has to be big enough for a nail (or pin) to fit in. Place the nail…

1000 Subscriber Special Steel Wool Science experiment

Science of steel wool photography, “The 9 volt battery is used to ignite the steel wool. Essentially it sends a current through the thin wire and it heats up, well under statement a LOT … to about 700 degrees celsius. These insane temperatures cause the iron to react with oxygen in the air creating iron oxide. This reaction releases heat, which heats up the next strand and so on, causing a cascading reaction across the steel wool. When you’re doing this remember the science.”   The chemical reaction requires oxygen. So fluffing it up and spinning it., increases the amount…

Fireproof Balloon Science Experiment

Balloons can pop rather easy. You know that they must be kept away from sharp objects and away from flames. Fire will weaken the rubber and will pop it.   However, in this experiment you will find out how you can hold a balloon directly in a flame without popping the balloon.   Light a candle and put the first balloon over the flame. Allow the flame to touch the balloon. What happens? The balloon pops, very quickly.   Light the candle again. Hold the second balloon directly above the balloon. Allow the flame to touch the balloon.   What…

Square Bubbles Experiment

Bubbles are round because a sphere is the shape that is the most stable for them—a sphere is more stable than a square or a triangle or any other shape. But when a bubble is surrounded by other bubbles, these “side” bubbles push against the “center” bubble, squishing until it has corners and sides—like a square! That’s what happened to your bubble.  

PING PONG BALL PHYSICS TRICK Experiment

Can you produce enough wind to blow a ping pong ball out of a funnel? It’s a Physics trick. See, the harder you blow, the harder it will be for the ball to leave the funnel, thanks to the Bernoulli Principle.   The way it works is the faster moving air creates less pressure. So when you blow through the funnel you create a current of fast moving air around the ball. That results in a low-pressure area below the ball that allows the higher pressure area above it to push the ball down and keep it from rising.  …

Genie in a Bottle Experiment

Warning 30% hydrogen peroxide can burn your skin. Adult supervision required. The bottle will get very hot.   The genie in a bottle demonstration shows a decomposition reaction. A decomposition reaction is when a substance is broken up into two or more different substances. In this case, hydrogen peroxide, whose molecular formula is H202, is being broken down into oxygen and water. Hydrogen peroxide is easily decomposed by light and that is why they are sold in brown bottles in drugstores.   To speed up the reaction, the compound manganese dioxide is being used as the catalyst. A catalyst provides…

Bicycle Wheel Gyroscope – Wonders of Physics experiment

A rotating bicycle wheel has angular momentum, which is a property involving the speed of rotation, the mass of the wheel, and how the mass is distributed. For example, most of a bicycle wheel’s mass is concentrated along the wheel’s rim, rather than at the center, and this causes a larger angular momentum at a given speed. Angular momentum is characterized by both size and direction.   The bicycle wheel, you, and the lazy susan form a system that obeys the principle of conservation of angular momentum. This means that any change in angular momentum within the system must be…

1) Divide the jelly belly into two groups (A & B). Each group should have one of each flavor. 2) Label paper with numbers 1-4 3) Place the jelly belly from group A on the paper. One jelly belly for each number 4) Put the jelly belly in from Group B into four cups so that your friend can’t see them. 5) Label these cups with the numbers 1-4. Make sure that the flavors of the group B have different numbers than the flavors from group A. 6) Tell your friend the names of the flavors they’ll be testing. 7)…

Brain Patterns experiments

What to do in this anatomy experiment. Pat the top of your head with one hand At the same time, pat your stomach with your other hand Keep patting your head, but start to rub your stomach in a circle movement Swap over. Now, rub you head while patting your stomach.   What’s happening It is easy for the hands to do the same pattern of movement. but it is hard to do two different movements at the same time.   Why is this? When you repeat the same movement, you get used to moving your hands in then same…

Bubble Snakes experiments

When you blow air through your Bubble Snake bottle, you are creating hundreds of tiny bubbles. As the air wiggles through the cheesecloth or towel, bubbles are continuously being made. The bubbles attach to each other when they come out of the fabric.   This is due to the surface tension of water. Surface tension of water tends to make bubbles unstable and due to this force they don’t last very long. But on adding soap the surface tension is lowered but still the bubbles aren’t very stable due to the force that water exerts on it so to reduce…
