This fun and educational science kit allows you to discover how to power a digital clock using only potatoes (then try apples and lemons – in fact you can experiment with all sorts of household objects to find out what other substances will power the clock!). Great for inquisitive minds. Potatoes not included!

• The Potato Clock uses a pair of ordinary spuds to power a digital clock.
• Not only for potato, others such as apple, coke-cola, juice and so on.
• This kit includes a digital clock, wires and prongs; two potatoes are all that’s needed to create a working clock.
• This kit is ideal for young science enthusiasts, and offers a valuable lesson on the transformative power of green science.
• Detailed assembly instructions included.
