A transparent base supports a large metal tip. The magician asks you to hide a very sharp metal tip under one of the glasses or under a paper bag. The now blindfolded magician holds his hand over the upturned glasses, under one of which the pointed stake is hidden.

When the magician feels ready he forcefully crushes the glass under his hand using all his strength. The test of courage is repeated once again. At the end of the act only one glass will be left intact, and after lifting it the magician will reveal the sharp stake beneath it. Made with great care and precision, it works electronically with 23A and CR2016 batteries.

It is completely removable for convenient use. The remote control, the transparent base and the pointed aluminum stake are supplied. Video instructions attached.
