What are they thinking?

There are some very strange products out there. The stranges thing I've seen lately are these disposable tooth brush like things that slip over your finger. They're made by Oral B. The purpose of them is to let you brush your teeth any time, any where. I guess they're suppose to be pocket sized so you don't need a toothbrush and tooth paste. You're still brushing your teeth with your finger! Honestly, if you're that concerned with brushing after every time you eat something....use a real brush. I'm sure its not very good at getting between teeth where you're going to have the most residue stuck.

Next...MythBusters. On the Discovery Channel there's a show called MythBusters which tries out various urban ledgends/other interesting myths/questions to see if they are actually true. When I first saw the show I thought it was great, but after I've watched more and more episodes, they really do a horrible job with some of the things they are trying to prove. A few of the shows are really good at providing information. The one tonight however was extra dumb.

They were trying to see what would achieve better gas mileage: driving with your windows down or AC running full blast on on a hot day. To do their test, they had two SUVs!! Okay, first of all, if you're concerned about gas mileage, maybe you should try something that gets over 12 mpg. Secondly, having the windows down will create more drag that's for sure, but a Ford Explorer isn't the most aerodynamic thing in the world. They tested it two ways, first they did 5 laps around a track with the windows up, 5 with them down, 5 with the AC running. This test showed that there was no difference between the AC running or not, and a .3-.4 decrease with the windows down. The second test is to have two explorers drive till they run out of gas. (They use 5 gallons of gas, but they have to pump the tanks empty, then fill them up, so...there's no way they have the same amount of gas in them). They found that the SUV with the windows down lasted 30 more laps(15 miles) than the one with the AC running at 45 mph.

A better test would be 2 high mpg cars. (No hybrids, since they don't get super gas mileage unless you're in stop and go trafic). This would give you something that is much more aero dynamic, and give you more range in your mpg rating to change.
