We can all agree that science is awesome. And you can bring that awesomeness into your very own home with these 20 safe DIY experiments you can do right now with ordinary household items.
1. Make Objects Seemingly Disappear
Refraction is when light changes direction and speed as it passes from one object to another. Only visible objects reflect light. When two materials with similar reflective properties come into contact, light will pass through both materials at the same speed, rendering the other material invisible. Check out this video from BritLab on how to turn glass invisible using vegetable oil and pyrex glass.
2. Freeze Water Instantly
When purified water is cooled to just below freezing point, a quick nudge or an icecube placed in it is all it takes for the water to instantly freeze. You can finally have the power of Frozone from The Incredibles on a very small scale! Check out the video on this “cool” experiment.
3. Create Oobleck And Make It Dance To The Music
Named after a sticky substance in a children’s book by Dr Seuss, Oobleck is a non-Newtonian fluid, which means it can behave as both a solid and a liquid. And when placed on a sound source, the vibrations causes the mixture to gloopily dance. Check out these instructions from Housing A Forest on how to make this groovy fluid funk out in every way.

4. Create Your Own Hybrid Rocket Engine
With a combination of a solid fuel source and a liquid oxidizer, hybrid rocket engines can propel themselves. And on a small scale, you can create your own hybrid rocket engine, using pasta, mouthwash and yeast. Sadly, it won’t propel much, but who said rocket science ain’t easy? Check out this video from NightHawkInLight on how to make this mini engine.
5. Create “Magic Mud”
Another non-Newtonian fluid here, this time from the humble potato. “Magic Mud” is actually starch found in potatoes. It’ll remain hard when handled but leave it alone and it turns into a liquid. Make your own “Magic Mud” with this video.
6. Command The Skies And Create A Cloud In A Bottle
Not quite a storm in a teacup, but it is a cloud in a bottle. Clouds up in the sky are formed when water vapor cools and condenses into visible water droplets. Create your own cloud in a bottle using a few household items with these wikiHow instructions.
7. Create An Underwater Magical World
First synthesized by Adolf van Baeyer in 1871, fluorescein is a non-toxic powder found in highlighter pens, and used by NASA to find shuttles that land in the sea. Create an underwater magical world with this video from NightHawkInLight.

8. Create A Gallium Masterpiece
Gallium has a low melting point of 29.7oC (85.5oF). By placing a lump of gallium into a warm glass of water, it becomes easily moldable into
