Tac Tick by Victor Sanz

Tac Tick, created by Victor Sanz and available through World Magic Shop, is a remarkable close-up illusion featuring an ordinary Tic Tac box. You start by drawing a simple design on the box’s exterior, which you then demonstrate can be easily erased. Next, the spectator uses the same pen to create their own design. After emptying the Tic Tacs, you can perform an optional bonus effect with them before making the design seemingly melt into the inside of the box—impossible to rub off! The only way to remove it is by inserting your finger into the box and rubbing it off right in front of the spectator. Everything can be thoroughly examined afterward!

Tac Tick includes all the materials needed to create your gimmick in under ten minutes, along with a bonus mentalism routine presented by David Penn and Jonathan Farr.
