Can through the hole

This is an illustration that works well as part of an assembly or even a group or club. You’ll need a can of drink - Coke or whatever is your fancy - and a thick sheet of card, hardboard or plywood. Whatever you use, it needs to be solid enough to be pushed and pulled without breaking, so if you end up using card, get the thick mounting board from an art shop not cardboard. The sheet needs to be about 70cm square. To set up, you’ll need to cut a perfect hole in the board exactly the same diameter as the can. This is the bit where patience and some useful tools come in handy. If it’s card, then a sharp art knife may do the trick. For hardboard or plywood, it’s a quick trip down to the local timber merchant to ask them if they’ll do it for you. (It’s more hassle but what you end up with will last a lot longer than card).
