3M spent 1,400 hours creating this sophisticated Rube Goldberg machine. The result is a wonderful maze driven by physics, chemistry and 25,000 Post-it Notes. The pendulums were both exciting and relaxing.
Hate when some permanently defaces your whiteboard with a Sharpie? 3M’s whiteboard eraser takes care of both permanent marker and dry erase stains with just a bit of water.
Awesome Stuff from Technabob, MightyMega and 95Octane
