Haha, I lost a piece of black board the other day~~

The board is from an air pump - warning people to cool it down after 12 minutes continuous usage (you know the principle of compression/evaporation, right? when ir or liquid is being compressed, it emits heat while it expands, it absorb heat).

When you made a sharp turn, you just happened to roll on the black board that I lost, therefore you thought your car was damaged.

Have a good sleep.
