Launching Your Rocket

Have a flight technician (or a kid) start pumping, and count the pumps as the launch sequence progresses. The bottle should fill with bubbles, and the cork will hiss a bit. After 20 or so pumps, you’ll reach ignition. (Once you’ve learned exactly how many pumps it takes, the next time you can start the countdown with that number.) The cork will explode out of the neck and the rocket will blast skyward. Keep an eye on it!

Now it’s time to send out the recovery team. If you built the rocket right, it will be far away from the launch base. If you had a successful flight, head back to mission control, break out the bubblegum cigars for your crew, and “refuel” for your next flight. If not, head back to the drawing board!
