Water Clock (Science Cube)
Construct a digital clock using two bottles of water (provided by you), and the included items of this kit - one insulated copper wire with a zinc strip and copper strip on opposite ends, one digital clock with two insulated wires, also with attached zinc and copper strips. Place the zinc and copper strips in the two bottles to complete your circuit and operate the digital clock. An included activity guide takes you step-by-step through construction and operation of your clock, and also suggests trying other liquids for different results. Assembling requires no special tools, just fill your bottles and begin - it's that easy! ~ Donna
Turn water bottles into a battery to power the digital clock! Just insert the electrodes into the filled water bottles and you will have a clock completely powered by water. Included in the kit are zinc and copperelectrodes along with a digital clock. Can also be used as a fruit clock! Instructions included.
