I'm building a baking soda/vinegar rocket powered car.  I'll be using a 2 litre plastic pop bottle with 
wheels.  I have figured out a way to suspend the baking soda and drop it into the vinegar after the 
cap is screwed back on but I need to find out the correct mix ratio and the what size hole to make in 
the cap to maximize the thrust.  Any advice?
