Help with assignment Industrial Design

[ayamegadeth69]

Hello,
I am trying to get accepted to Industrial Design college, and they gave me a very challenging assignment to make.
The subject is a rubber band-it can be any kind of elastic band (hair,office etc.)
and the purpose is to make an object (no matter from what material, but something not too big) that can be used, and is not usable without the elastic band-this should be the main function of the object. Note that it can't be just an ornament, but a functional object-like you obviously should make as an Industrial Designer.
I would really appriciate if you could give me a clue or at least some lead on this. I am thinking about it all the time but still can't find a lead.
Thank you so much!

It was either that or the rubber band ball. The ball method got a bit wordy.
