Balloon Momentum

What happens to helium and air-filled balloons when you speed up or slow down? Check out this video to find out and learn why?

This is similar to the difference in behavior between electrons and holes in semiconductors. Holes are an absence of an electron (kind of like the helium-filled balloon, which is an absence of mass). Electric fields accelerate electrons and holes in different directions due to the presence or absence of negative charge.
