Instructables

Self-closing box

I saw an instructable where a box has a toggle switch, and when hit, the box turns the switch off. I can't for the life of me find the instructable now. What is it?

Websearch "most useless machine". I'm not sure "most" is actually in the title. There have been several versions; the simple analog approach is the one which I found most entertaining.
Thank you i have been looking for this! :)
