Exactly, Hot wheels uses the idea as well as those machines that shoot
tennis or baseballs for practice. The baseball ones use a boat trailler wheel
driven by an electric motor. Just make sure the spinning wheel has
a large mass to keep its speed up when the ball comes in contact.

I like the idea of using wheels to accelerate the balls. I believe when I
was a kid one of my friends had a Hot Wheels car wash or somethingorother
that used the same concept to move the little cars around a Hot Wheels
track. Certainly worth trying. I think the balls are so light, though, that
using several sets of wheels might be pointless--it's not like having to
accelerate a large mass.
Thanks!
