Bio-Clock – Tell the Time with Ketchup

by

Bio Clock

This is a cool educational gadget, the Bio-Clock. It’s a digital clock with infinite different power sources.

The versatile Bio-Clock demonstrates how simple chemical reaction can create usable electricity. Add almost any household materials to its electrodes and this amazing clock has the power to run accurately and non-stop. Ketchup, toothpaste, lemons, even cola works well.

Experiment with your own unexpected power sources!
Easy to assemble; extra electrodes and instructions included.

If you want a fun way to educate the kids it’s available from Museum Tour for $14.95 (batteries not included :)), thanks to vousami from our forums for the tip.
