Coinvexed Third Generation (David Penn)
In David Penn's double coin bend routine, a spectator signs a coin, which can be borrowed. Then something very extraordinary happens as they feel the coin bend within their own hands. The reactions for this are incredible as the coin is also signed! A second signed coin then bends whilst being isolated under their palm, on a table top. The spectator can then keep the coins as a souvenir, which freezes the moment for them forever.
