I need an easy project that has that "wow" factor. It's gotta be about kinematics, forces, energy, sound, or electricity.
Study very hard for an ACT exam
Go for a tour of duty in the army
Get a serious injury
Take the ACT exam with skills
Get good score
Send in application to MIT saying you had depression from injury
Get into MIT with priority
Drive a car off a bridge with you in it and calculate the force that is exerted on your body, the speed you are travelling when you hit the ground, and throw in a cool little bit where you calculate the mass of the earth using your mass. It'll have quite the wow factor. Fortunately this is pretty basic kinematics so you should be able to do it before you perform the experiment, because it's pretty hard to do calculations when you are dead.
Do the thinf where you poot a black chalkboard over a speaker and play a frequencyand put shuffleboard salt on the board aand watch it make batterns
I have a phd in clarinet
If at university you could go for the Meissner effect. Easily done, always a success. I have done it many times and the wow-factor is sky high.
If not you could demonstrate a Stirling engine. A machine that runs off the heat from your palm is quite impressive.
