DIY Science Experiments You Can Do at Home
One card per experiment. Make the thing, watch it happen, then turn the card over for the mathematics and physics that made it work.
01 · Kit
Everything is in a kitchen, a drawer or a recycling bin.
02 · Method
Step by step, each with why it works and what to watch for.
03 · Science
The physics and chemistry, with the numbers worked out.
04 · Real life
Where the same idea is quietly at work around you.

Card 02 · 15 minHow to Make an Underwater Volcano: Convection in a Jar
Hot red water in a salt shaker, lowered into a jar of cold water. It erupts, curls into a mushroom, and lies on the surface like oil, because water one and a half percent lighter has nowhere to go but up.
