Q1: How can you use an elastic band to make things move?

[Answer]

We have looked at how elastic bands can make things return back to where they started.

We can use elastic bands and elastic sheets to make things move, too.

For example, we can jump up and down on a trampoline to get extra height.

We can also use an elastic band to make things move forwards – a kind of elastic engine.
