help in project

hello, i'm amit.

i'm a freshman at BGU and it's my first project at my material engineering studies.

me and my partner Omer had a great idea.

an eraser made of two major subjests, a rale and a stick connected to it, to which a sponge is connected.

that will make it more effective and quicker to erase the board.

We'd like to know if you have any more ideas for our project, moreover we'd like to be helped by choosing the right materials (including costs).

thank you in advance.

amit and omer.
