Pinwheel Spiral Spinner Experiment

In Atal Tinkering Labs ATL | No comment

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

In Atal Tinkering Labs ATL | No comment

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

In Atal Tinkering Labs ATL | No comment

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

In Atal Tinkering Labs ATL | No comment

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?

In Atal Tinkering Labs ATL | No comment

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…

1000 Subscriber Special Steel Wool Science experiment

In Atal Tinkering Labs ATL | No comment

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

In Atal Tinkering Labs ATL | No comment

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

In Atal Tinkering Labs ATL | No comment

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

In Atal Tinkering Labs ATL | No comment

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

In Atal Tinkering Labs ATL | No comment

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

In Atal Tinkering Labs ATL | No comment

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…

Bubble Snakes experiments

In Atal Tinkering Labs ATL | No comment

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…

Balloon Center of Gravity Experiment

In Atal Tinkering Labs ATL | No comment

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…
