Improved title grammar as it is in the Hot Network Quesions tab.

Tape a straw to it and run a string through it. Tape the string across the room and now it's a guided rocket. You can play with various nozzles but putting different sized straws into the opening in the balloon which will allow you to vary the size of the contraction. | |

motors are not the same as engines; fun fact: unwieldy images can be made smaller by changing the link

fixed formatting, added image
