Watch this video. If your parents allow it, try to create the bottle with pennies and a rubber band. How does this simple machine store energy? Can this relate to the toys we were playing with today?
I see that when you roll the bottle when the rubber band and pennys are inside, the sting rolls around itself and when you release it it will roll backwards because the string unrolls itself and pushes the bottle backwards. This is called CHEMICAL Energy.Youssef
I think that that's like a toy car because you have to give it energy. Then when you release it, it goes further then the amount of energy you gave it.-Freya
If you push a rubber band in the bottle it windes up and comes back.-Why does the rubber band come back and how does it come back -Posted by Maheeka Sabharwal
I think it is related to the toys we are playing now.there is lots of toys that has spring inside, and there is lots inside the simple machine also. Minkyoung
I think that this energy was first made by your hand. How I think it works is that the weight makes the rubber band twist if there was no light it would not bend because nothing is forcing it down.Nusayb
I saw that the bottle has the coin it move to another place and it went back to him.Sebastian
