Lifesaver kit

Kit contains:

A Rubber (eraser)
A marble
An elastic band
A piece of string
1 penny

Can you work out what each is for?

This was given to me by a friend (you know who you are ;) ) kinda thought I needed it today as I've been marking again... currently at 5/24... meh, taking an age!


Ok, I'll give you a hand... the rubber is for erasing your mistakes :)
