Backyard Roller Coasters: get your DIY on [Video]

We stumbled upon this GIF of a little kid enjoying a ride in a DIY backyard roller coaster, I mean, is it the coolest thing or what?!

We then proceeded to fall into a weird loop of Youtube videos and bad blogs. Seems that people in the US freakin' love backyard engineering!

There's actually a dad who took the concept further and started a backyard roller coaster company! Ha! Way to go Will Pemble!

Some of these DIY roller coasters features include a 20ft. drop, that's the real deal.

Others are not DIY at all and are pretty much expensive toys for rich baby boombers. Ugh.

And sometimes people just don't get their maths and physics straight and it ain't ever gonna' work.
