Crazy tic tac bounce!? | EVERYDAY MYSTERIES

I think you actually accomplished the second experiment with the first all together.
when the tik-tak bounced off, with a lot of spin and then reaches the highest point in the curve, it falls back down naturally without  additional downward momentum and then looses its spin when translating it into upward momentum and reaches multiple times higher that the highest point of the previous curve.
So its the same as letting it fall down from your fingers with a spin, only that you can reach a much higher spin.
