Friday's Video of the Day features a holiday themed Rube Goldberg Machine.
It's a really complicated machine designed to do something really simple, like light a menorah for Hanukkah, with lots and lots of steps.
The whole process involved some robots, Legos, helium balloons, toys and nitroglycerin.
The machine designed by engineering students at the Israel Institute of Technology.
Hanukkah begins Saturday night at sundown.
