Need a bit of help!

Right im doing physics A2, i dont know what that level of education that is in america its like for the age group 17- 18 here

Anyway, i need to do a physics essay, and it can be on ANYTHING to do with physics, thing is i dont no what to do it on, cos there so many stuff, i want to do something really interesting tho!

appararently u cant do time travel or black holes cos theyve been done to many times, and everyone one has been rubbbish

so if u can think of anything cool to do, give me some ideas!
