Do you have a curious mind and a love of science? Here is a list of easily put together experiments you can do at home!
1. Crushed Soda Can
Get a 12 fl oz pop can and empty it. Put a little bit of water into it. Not much, maybe less than 1/4. Heat on the stove top until the water on the inside is boiling. Now take it off the heat and put the can into a bowl of ice cubes. If done right the can will crush itself. I always put the can in the ice upside down. Use tongs to take the can off the heat.
2. Corn starch and Water:
Mix corn starch and water to create a non-Newtonian fluid. When left alone it will act like a liquid but when acted upon by a force it will react like a solid. If you hold it in your hand it will run through your fingers but if you punch the fluid it will harden.
3. Mbius Strip
Mbius Strips are totally mind-bending, and super fun! The surface of the strip is just one single edge. What does that even mean?
4. Penny and Nickel Battery
Light up an LED with just a bit of pocket change!
5. Egg in a Bottle
Not the most practical necessity here, but this is seriously cool. See how to get a hard-boiled egg to fit through the rim of a bottle!
6. Film Canister Rocket
Make use of those old film canisters, by firing them at your enemies!
If you can find old empty film canisters and some alkaseltzer tablets:
Put 1/4 of a tablet in the film canister, fill it half way with water, cap it, turn it over and put it down.
You now have a rocket!
7. Soap, Milk, and Food Coloring
This is seriously trippy. Looking into the dish will make you see into the future.
8. Exploding Volcano
An obvious classic. A vinegar and baking soda volcano is a staple of science fairs, and is hours of fun.
9. Dry Ice Experiments
You can do all kinds of cool stuff with dry ice. Here are a few of them.
– Add some dry ice chunks to an open top aquarium or other container. Blow some soap bubbles into the container a couple of minutes later and watch the bubble float on the carbon dioxide gas that has been produced via sublimation.
– Add dry ice to a cup of warm water and check out the fog that is produced.
– Drop dry ice and water ice onto a hot pan. Compare and contrast melting to sublimation. Neato!
– Place a chunk of dry ice on a penny and gently add pressure. It will scream like a banshee.
– Place warm water and a chunk of dry ice into a resealable plastic bag. Seal it up. Watch. It might pop the bag after some time but it won’t hurt anyone (though it might be loud)
– Place dry ice in a balloon (stretch out the balloon first and get it nice and loose).
– Add a small quantity of water to a counter. Maybe put a penny in the puddle. Then add a good size chunk of dry ice to the equation. It will freeze the puddle solid.
Safety: Dry ice will kill skin cells. Never store dry ice in an air tight container.
10. Cloud in a Bottle
Trap the atmosphere in a bottle for easy transport!
11. Rainbow Liquid Density Experiment
This experiment is definitely the prettiest. Feast your eyes…
