HOW TO SUPERCHARGE YOUR FUELER just cut up some copper wire and remove the black or red covering to the wire chop it up some more then put it into your fueler!!!

Uhhh....are these RC's? How fast do they go?

Chuckster...

no they arent RC, i think they just go in a straight line.

Screw vinegar and baking soda, go the dangerous route! 110 octane, baby! :D No wait, better yet, racing nitro! 95% nitro! No, 100% nitro!

how do they work?

Okay, I got one. here's the 411. These cars are about a foot long and six inches wide. It comes with a little tester and a NOS bottle. THE CAR DOES NOT BURN ANY KIND OF FUEL AT ALL. You either test the liquid with the tester or fill the NOS bottle with it and stick it in the car. The car uses 3 AA batteries and it passes a current through the liquid which tests it for acidity, neutralness or base. If the mix is an extreme acid then it gets a 5 on the 1-5 scale or a -5 with an exteme base. If it gets a 0 it's neutral and does not run. It's supposed to run faster for each level of acidity or base -5 to +5 with -5 adn +5 being the fastest. I used bleach and it got a +5 and then I ran it. I then used some Coke which got a +3 and ran it. I could tell no difference in speed.

Verdict: The car costs $20 and comes with the tester and packets of fizzy mix stuff. The motorcycle costs $10 and comes with no tester and no fizzy mix stuff. Get the motorcycle, the tester and the mix are useless. The car is not worth $20.
