A couple reviews state that "frenel" lenses don't exist - true, it is spelled fresnel but it is pronounced in English as fray-nel. The Fresnel lens was invented by French physicist Augustin- Jean Fresnel. The French would pronounce it freh-nehl. So please first check your knowledge of how something is spelled/pronounced. I gave this show a 10 because I'm tired of shows like Mythbusters. Kevin and Grant take failed experiments from YouTube and do it so that it DOES succeed without the damage it causes to the YouTube users. And its a limited budget. It is two buddies working out of a garage, having fun and seeing how far they can go to make something succeed. They made a 400lb concrete boat float!!! I want to know how many people can do that without knowing the science and math to make it actually work! What a breath of fresh air for a show. My whole family loves it!

Hate this show. Just rubs me the wrong way with all their constant namedropping of 'science'. This is nothing more than an excuse to do stupid stunts or destroy stuff. It has only the most insultingly threadbare relationship to anything 'scientific'. "Watch us launch these garbage pails with a homemade catapult. Oh by the way, it's 'scientific' because we (i.e. someone off-camera) used a simple 7th grade math formula to guess where they'd land." What else is there to say? Nothing, but I have to write 10 lines about this show. There's just nothing much to the show to begin with, so it's hard to come up with that much to say. There, finally did it.

Although the fun aspect of the show is good there science seems off. it would not be difficult to do better on a smaller budget. they may be teaching basics to beginners but there not teaching anything new or reaching there tasks potential just a bit more thought could have been put into the production of the show and the way they go about thingsIf its a show for educational purposes they don't need to resort to large amounts of gunpowder or other high velocity items to teach . They just need to get there methods right . In the right hands compressed air is cheaper more environmentally conscious and a lot safer than explosives or liquid nitrogen . They also seem to be condoning doing power slides ( but not really power slides) in what seems like a public place

These guys are definitely not smart. They seem to know nothing about science or cars or common sense for that matter. Several times they called a "fresnel" lens a "frenel" lens. Sorry guys, no such thing. Then, they are going to power slide a car to parallel park. What they were doing was an e-brake skid, nothing more. My 5 year old daughter knows how to do that! A power slide is akin to a drift. After watching one show, I can tell you these guys can't drift. These guys could screw up a wet dream! If you are completely clueless like these guys, you may find it entertaining. On the other hand, if you are any smarter than a doorknob, this show will make you hope they are sterile and can't procreate.
