About this document

Whistling Wallet Invention Explained by Rickert Osbert Vasquez Sanchez is a document available to read on EtoBox.

Larry has invented a "whistling wallet" that whistles if you sing near it to help people find their lost wallets. He gave some to friends but two were angry after their wallets made noise during a concert bothering other attendees. Larry still needs to improve the wallet before it can be commercially available.
