Todesstuhl Milko Bräuer

This spectacular effect is only for the brave..
When the magician gets captivated by the audience, the chain holds his body and legs. Everything will be sealed with a major lock.
Now time is running out as the saw begins to turn and the second gallon fills with water.
The magician has to leave the chair before the weight of the second gallon is heavy enough to make the saw crash down.

Your fate is in the hands of only one person from the audience, who gets 5 keys from your assistant. The person from the audience has to decide which key to choose and pass over to you.
The final key will open the lock and save the magician right before the saw crashes down only a moment after the magician left the chair. (of course there are several assurances involved which will protect you! The saw only falls down when the magician really left the chair!)
