How do I make an elastic powered vehicle which will transport and egg 2 metres up a ramp with a 35 degree angle?
Basically, we must use an elastic band and there is no catapult allowed. The ramp is very steep and we can't use batteries or anything.
We were thinking something to do with weights. Please help!
We tried knex, but it ended up being too light.
And it needs to go against gravity!
