What is the name of the raised bumps that cover the striking area of a table tennis bat?

Question

In modern table tennis it is a common practice to acting the fool when the match is almost over. I.e. players used to flip the side and play a little bit awkward analogue of table tennis when you need to hit your own side and not the another one.

Answer 1

Pimples will cover the striking area of a table tennis bat. Table tennis rubbers can have the pimples (pips) facing outwards or inwards. Pimpled rubber (pips) has the pimples facing outwards which means that the smooth side of the rubber is attached to the sponge. So you strike the ball with the pimpled surface.
