1. The problem statement, all variables and given/known data Make an object that starts from ground that does not use any liquids or springs that will jump off the ground taking everything that is attached to it with it. 2. Relevant equations None. 3. The attempt at a solution I have created a water bottle with some wholes at the bottom. Tied a bunch of elastic bands around it. Now the way I thought to bring it up was Use some kind of (Stonehenge) type looking object so when you pull down on the bottle to touch the ground, their will be enough force for the bottle to go straight up and bring the (Stonehenge) object up with it. My Problem here is the weight of the objects. I doubt the bottles will go up with enough force to bring up whatever is attached to it.
