We are all makers

Oobleck is a delightful non-Newtonian fluid that exists as a liquid under low-stress situations, but becomes more viscous when agitated, either by hands or by vibrations. Named after a fictional green precipitation in a Dr. Seuss book, the substance is fun on its own, but you can add more awesome by making it glow (with highlighter dye, under a black light) and making it perform (by placing it on a speaker). You’ll be amazed as it assembles itself into abstract patters and creature-like forms!

I’m sorry but instructions are not clear for beginners. My daughter and I wanted to do this project after seeing it in volume 41 of you magazine, but it does not make it clear how to get frequency from computer to the subwoofer. I see clips used on speaker end, but what do you use on computer end? Thanks.
Sorry to get back to you so late. We just used an online tone generator. This allowed us to adjust the frequency up and down. You will also need some sort of amplifier in order to power the subwoofer. Hope everything worked out!
This one works great – http://plasticity.szynalski.com/tone-generator.htm
Thanks for the reply. We end up using an iPhone app for frequency, and using 3.5mm headphone jack to RCA, then to speaker wires to the subwoofer.
