This is an instructable of how to make a big elastic band ball.
Step 1: What you need
All you need is some Aluminium foil and some rubber bands (or elastic bands- your preference)
Step 2: Step 1:
Grab a sheet of Al Foil and roll it into a ball about 2 or 3 cm's diameter (distance across the centre)
It doesn't matter if it is a bit deformed, that straightens out.
Step 3: Step 2:
Start to wrap your ball in rubber bands by stretching them around. At the start I normally need to double mine over. It will take a bit of time but eventually you can do it without looking so can watch tv while doing it. Keep goind until it is your desired size. This image has about 5 bands on it.
Step 4: Step 3:
When you are done it can be kept on your desk, bounced, rolled or anything you want to do with it. The largest ball ever was about 910.8 KG (2,008 Pounds) and made by a person called John Bain. My friend made one the size of a small netball. So enjoy your rubbery goodness.
(P.S. it is not tin foil as it is made of aluminium)
