Hi for my english class, we have to make an invention using cheap material that is useful, original, and provides a solution to a problem. We actually have to show the class like a prototype of it and I have no idea what to do! Mines on tuesday and I'm so stressed over it. (My idea was to make something that separates plastic and paper for a recycling bin, but i have no idea what i would make..so please help provide me with more ideas for inventions).
For your idea, you could do something with water. Once water hits a mix of plastic and paper, the paper will disintegrate and sink, and the plastic stuff will be left.
How could you demonstrate that, do you think?
Sorry but someone already did that they used a plastic cup of water and a straw and filtered out the dirt/impurities...you have any other ideas?
Nope -- sounds like a science fair thing to me.
You might try googling for science fair project ideas and see what pops up.
It's not a science fair project its a creative studies english class...it can be anything that has a solution to a problem, new or useful. Please I seriously need help on this, I am so stressed you have no idea.
