Welcome to our Friday quiz!

Today we’re going to be looking at rocket engines. Good Luck!

This quiz will be available, but prize eligibility will end on Sunday at midnight US EDT.

This quiz, one prize: (drawn from the high scores): One copy of our Liftoff 2-DVD set. (If you already have this set I will make a substitution)
