Evolution by Rus Andrews is an impromptu approach to the classic cap in bottle effect.Imagine being able to take an empty beer bottle from a random table in a bar or nightclub, then taking any bottle cap, perhaps from behind the bar or from another drink…Have the spectator sign the cap and then, visually, whilst the spectator is holding the bottle; penetrate the cap through the bottle leaving the signed cap inside.This can then be given to the spectator and kept as a souvenir.
