Moon-crater impact tray

Drop pebbles into flour and cocoa from marked heights to make lunar craters

How did the Moon get its craters? Fill the tray with 3 cm of flour, dust cocoa over the top, and drop a marble from the 10 cm mark on the back board, then from the 20 cm mark. Each impact punches out a crater and throws white flour across the dark cocoa in bright rays, just like the rays round the crater Tycho. Compare sizes, heights and weights, then smooth it over and start again.
