Yes, many kids, teenagers, adults are now back in school, but that doesn’t mean the fun is over. Here are five mind-bending science experiments that are not only fun, and mostly safe, but might leave you puzzled as well. Continue reading to see them all.

5. Giant Dry Ice Bubble

I used: Dawn Dish Detergent 5 tablespoons; Glycerin (95%) 4 tablespoons; Distilled Water 1 cup. Stir it really good but try not to stir up any bubbles. I used 100% cotton for the cloth strip. Dry ice.

Be sure to wear gloves when handling the dry ice. It was definitely easier to make a bubble across the smaller bowl. If you try to make a bubble across a large bowl, you may have to try many times until you get lots of the bubble solution coating the edges.

4. Double Slit Experiment

Light is so common that we rarely think about what it really is. But just over two hundred years ago, a groundbreaking experiment answered the question that had occupied physicists for centuries. Is light made up of waves or particles?

The experiment was conducted by Thomas Young and is known as Young’s Double Slit Experiment. This famous experiment is actually a simplification of a series of experiments on light conducted by Young.

3. Resonance

So this experiment is the Chladni plate experiment. I used a tone generator, a wave driver (speaker) and a metal plate attached to the speaker.

First add sand to the plate then begin playing a tone. Certain frequencies vibrate the metal plate in such a way that it creates areas where there is no vibration. The sand “falls” into those areas, creating beautiful geometric patterns. As the frequency increases in pitch the patterns become more complex.

2. Elephant Toothpaste

The elephant toothpaste chemistry demonstration is a dramatic demo which produces copious amounts of steaming foam that sort of looks like the toothpaste an elephant might use.

1. Sound and Water

This is a really fun project and when you first see the results, chances are your jaw will drop. The main thing to keep in mind for this project is that you need a camera that shoots 24 fps.

The effect that you are seeing can’t be seen with the naked eye. The effect only works through the camera. However, there is a version of the project you can do where the effect would be visible with the naked eye. For that project, you’d have to use a strobe light.

Bonus – Instant Ice
