You bring out a chain and a lock which may be carefully examined. There’s nothing to find.
Spectators tightly bind your arms with the chain and then lock it.
In no time, you've escaped, usually under some cover or by momentarily turning away. This one is easy to learn and perform.
The chain escape is often sold under the name "Siberian Chain Escape" and costs about $12. It's also included in some magic sets.
