1. Homemade Roller Coaster
With theme park admission prices increasing every year, enjoying roller coasters is a privilege that many just can’t seem to budget. Fortunately, a very skilled amusement park fan decided to build his very own coaster.
Located on a 10-acre plot southwest of Oklahoma City, Jeremy Reid built an incredible roller coaster in the backyard of his parents’ home. It cost Reid $10,000 to build and features a 16-foot drop that propels riders — friends and family — to speeds in excess of 15 mph. (Link | Via)
2. Homemade Jetski
A brilliant Chinese inventor by the name of Tao Xiangli has come up with an amazing idea of building a submarine using minimum resources and costing a stunning low amount of cash. It took the 34 year old a couple of years’ hard work and a little over four grand to get the whole underwater mission complete. His submarine is made up of propellers, electric motors, a periscope, and a depth control tank. The best part is that it cost just about $4,385 to build. (Link | Via)
