This Rube Goldberg machine takes it to an all new, super awesome level where mirrors and magnifying lenses work together to accomplish some very impressive things. Using light as a tool in a Rube Goldberg machine is super cool. The video is part of a campaign by Japanese firm au HIKARI.

Start them young: Playset teaches kids to take care of a real car

The world offers a lot of lovely toys for children, and while we love the usual, the practical ones have a special place in our heart.

Tasks include various things like changing the oil, swapping the air filter, checking the dipstick, removing the spark plug, and of course, checking various nuts and bolts.
