Several quarters penetrate a brass block one at a time. This happens under the closest scrutiny from spectators - which can surround the magician as the effect is performed.
The brass block is wedged in between two brass rings and the quarters are dropped on top. There is apparently no way for the coins to penetrate the brass plug. Yet that is exactly what happens. One by one, the quarters filter through the block as if it were a sieve. >p>
