My son is doing a science experiment consisting of building a self propelled car model (can be a rocket or some kind of other vehicle). The car model must travel 1.5 meters and stay within a couple of feet (it should not get off a straight course by much). His idea was to put wheels on a diet coke bottle and drop a couple of mentos in it to propel it. Again, it has to be self propelled (no running it down a ramp or anything).
Any ideas would be greatly appreciated. I know there are a lot of homework questions out there just trying to get out of their own homework, but this isn't one of them. The work is in the experiment this time.
Thanks in advance for any insight!

Rubber-band powered cars would work here. There are plenty of sites on the web that describe these. Just do a search for 'rubber-band cars'.
Best wishes and good luck.
