Magnetic Slime(Ages 9-16)
Pull together a batch of magnetic slime!
Polymers are really big molecules, made up of lots and lots of smaller molecules joined together. They can make materials bouncy like a rubber ball, stiff like a plastic toy, or stretchy like a piece of gum. One great way to play around with polymers -- and to do some hands-on experimentation with chemistry in general -- is to make your own slime.
In this experiment, we uplevel your standard green goo to jet-black magnetic slime that will magically move and dance without you even touching it!
Follow along below or in our How to Make Magnetic Slime video tutorial!

Erupting Apples(Ages 3-8)
When you have three little curious boys running around your house and a free afternoon, why not get a little messy and do some kitchen science? We did ours in the backyard and let the whole thing become a super sensory experience. When they inevitably try and find the remains of their apple in the mound of foam, be sure to ask them what it feels like.
