Tables.

I'm starting to gather bits of this and that to come up with a foolproof topic.
..TABLES.
What I'm thinking I'll do is, I'll look up the different inventions/discoveries of tables (material, structure, uses) and then attempt to build some diferent ones myself, out of cardboard.
(DIY!!!)
I could have variables such as material, area of base (surface kept the same), and how the base is structured.
annnd then I could see how many Mars Bars the 'tables' with dif bases can hold, to test their strength, etc.
I could base my observations on the area of the base in ratio to the area of the surface.

This doesn't sound too bad..
NB: this so called tables of mine are only going to be the size of a tissue box, I don't plan on physically using them..
