What can I make with this kit?
If you love scaring people with creepy crawlies, this is the kit for you. Build a walking spider from the 46 parts and watch it skitter across the floor. The kit is suitable for children aged 8 and over with adult supervision. It clicks together with no need for batteries, glue or soldering. However, a crosshead and slotted screwdriver, diagonal cutters (recommended Order Code A20QW )) and small stick may be helpful.

How does salt water power a spider?
Have fun learning about alternative clean energy with this cool salt water powered spider (model number 21-751). Salt water fuel cells create power by using a chemical reaction between a magnesium strip and oxygen. The salt water is a catalyst for the reaction. Add salt and water in a 1:5 ratio for the most efficient mix, experiment and see how the salt level in the water effects the bike. Place four or five drops of salt water on the fabric and watch the spider go for up to 15 minutes. Spare fuel cells are available - Order Code N43DQ.

The materials used are environmentally friendly with no toxic substances or chemicals used.

Rated 1 out of 5 by from Salt Water Spider - Far too fiddly Nice idea, but the reality is this is far, far too fiddly for a child to assemble. I managed to get it to work in the end and when it does finally work it works well, but you'll need a huge amount of patience to get to that point.
