My hypothesis is when i drop the paper helicopter and change the mass of the helicopter so it can change how fast the helicopter comes down or to make the helicopter come down slower.

Equipment:

Meter stick , clamp, helicopter, stopwatch.

So my method would be to setup the clamp and set the meter stick so that if i use a human being there hands wouldn’t be shaking about so then i will get some one to use the stop watch to time it and then i will countdown to 3 and then drop it.

It would help people because the material would be cheap and there for that makes the product cheap, it would be fun for children.

this could go wrong because of the material and it could be a bit weak and it could break easy but to prevent this i could put a cheap but heavier material which prevents it from falling apart so this object could be used over a long period of time and prevent less complaints which will keep customers happy and get good comeback.
