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…

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…

You can fill the bag by holding the mouth of the bag at arm’s length. and blowing once directly into the bag. The entire bag will inflate in one breath.   EXPLANATION The Windbag is a long, narrow plastic bag that is about 8 foot long and about 8 inches wide. The bag can be blown up the old fashion way like Grace tried in the…

Balloon Center of Gravity Experiment

The balloon without the coin is easy to move, but the balloon with the coin is not that easy to move and control.   Why is this? When you toss the balloon with the coin in the air you can’t tell which way it’s going to go. This is because the balloon center of gravity.   The center of Gravity is where the majority of and object weight is located. In the case of the empty balloon it’s leaning towards the mouth and with a ball its in the center.   Because the coin adds more weight to the balloon…

Can you put a Ping Pong ball into a glass? Experiment

RULES No moving the cup No touching the ball or scooping the ball No sucking the straw (You can blow into the straw)   Grace is blowing air into the straw and is flowing out of the funnel at a high velocity. The ping pong ball is placed under the funnel, the low pressure created by the high velocity air going around the ball will keep it in the funnel. Once Grace stops blowing the ball will fall out of the funnel.  

The Paper Helicopter Experiment

Cut along the SOLID lines. Fold along the DASHED lines. Fold flaps C and D inward, then fold the bottom up; this will create a handle of sorts. you can also make your own design like Grace did. Let us know in the comments below how long it took your helicopter to go down.   EXPLANATION As a result, there is less air pressure on top of the wing; this causes suction and makes the wing move up. A helicopter’s rotor blades are wings and create lift. An airplane must fly fast to move enough air over its wings to…

Baking Soda & vinegar exploding bag!

AWESOME! No other words for this experiment. We all know what’s going to happen, but when. If your bored and have nothing to do then this experiment will add some excitement to your afternoon.   What happens inside the bag is a chemical reaction – the baking soda and the vinegar eventually mix (the paper towel buys you some time, as it’s like a fuse) When they do mix, you create an ACID-BASE reaction and the baking soda and vinegar work together to create a gas, (carbon dioxide) The carbon dioxide starts to fill the bag, and keeps filling the…

Static Electricity with soda can Experiment

First start by rubbing the balloon on wool or your hair or your dogs hair.   When you rub the balloon on your hair, tiny parts of the atoms in your hair, called ELECTRONS, collected on the balloon. These electrons have a NEGATIVE charge. Now that the balloon has a negative charge, it is attracted to things that have a POSITIVE charge.   When you bring the negatively charged balloon near the faucet it is attracted to the POSITIVE force of the water. The attraction is strong enough to actually pull the water towards the balloon as it is flowing!…

Electromagnetic Experiments

Use a cloth or gloves, as the battery will get very warm. Grab the ends of the battery with your gloves or cloth and try to pick up some metal objects.   Now the iron nail has become a magnet. This is really awesome.   Because the electricity flowing through the copper wire it passes through the iron nail. This makes it magnetic, Electromagnetic! When I remove the battery it is not magnetic anymore, this is because electricity is not flowing through the copper wire without the battery.  

Electrostatic Toothpick Experiment

Now I blew up a balloon, and rubbed it across my hair (freshly washed hair works best). Now we have a negatively charged the balloon. You can test your balloon by seeing if it will raise the hairs on your arm, if it can then your ready. If not rub the balloon more on your hair. If you don’t want to rub it on your hair, try your dog they love it.   With my balloon negatively charged and bring it closer to the cup….. The toothpick moves. The positively centered toothpick is attracted to the negatively charged balloon, which…

Static Electricity Butterfly Experiment

What makes the butterfly move its wings? When we rubbed the balloon onto our hair, or carpet the electrons were lost from our hair/carpet and gained by the balloon giving it a static charge. When the negatively charged balloon gets close to the positively charged tissue paper they are attracted to each other, and the pull of attraction is so great that the lightweight tissue paper moves toward the balloon.

GELATIN STALAGMITES experiment

Procedure Pour a small pile of unflavored gelatin on the tabletop or plate. Rub a balloon in your hair and bring it near the gelatin.   Explanation The particles of gelatin will arrange themselves in columns resembling stalagmites as the charged balloon is brought near. The gelatin particles are normally neutral, but become temporarily polar when brought near the balloon. The negatively charged balloon repels the negative charges and brings the positive charges closer to the surface of the gelatin particles. The polarity is transmitted to the neighboring particles, until you eventually have a long chain of molecules held together…
