Make Your Own Diving Fish: A Science Experiment

 In this "diving fish" experiment, your kids learn about bubbles and buoyancy.  I'm glad to see the video is getting a good number of views. My "assistant" was totally engaged and curious, and loved doing the experiment by himself.

I hope many of you are experimenting at home! When it comes to playing in our kitchen "lab", I like to see how things work for myself. (That's code for I rarely read and follow instructions.) But just in case you want to get your bearings, ghere for the step-by-step instructions. 

In short, you add baking soda and vinegar to water, and try out different small foods to see whether they sink or float!

Raisins are the standard, but they're on the big side of what works well. My son called raisins "flounders" since they mainly stay sunk. Smaller foods like barley, buckwheat groats, beans, etc. were way more exciting to watch zipping up and down.

Have fun experimenting in the kitchen!
