'Evolution' 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.
For those that do not want to perform the impromptu un-gimmicked effect we also supply you with a gimmicked version that you can use to perform the same effect.
"Beautifully Devious" - James Brown
"The cleanest and most natural impromptu cap in bottle that I've seen in years, I'll be using this for sure!" - Richard Bellars
"The combination of a devious principle and clever psychology make this effect a real winner! Probably the best impromptu cap in bottle routine I've seen!" - Cameron Francis
