BOTTLE ROCKETS

Aim: To launch a functioning vinegar and baking soda bottle rocket with the intention of staying in the air the longest and having the most creative design.

Equipment:

• 1.5L Plastic Bottle
• Tape 
• Cork
• Pencils
• Cardboard
• Something to decorate
• Baking Soda
• Vinegar

Method:

Not our rocket

1. Take the empty plastic bottle and discard the cap. Next, take the pencils and tape them to the side of the rocket so they extend past the mouth of the bottle. Wrap the tape around these pencils more to stabilize them, these will act as your stands.
2. Make sure your cork fits the mouth of the bottle and it isn't too big or too small.
3. Add a cone made out of cardboard and paper, try to make it thinner so it is more aerodynamic and can fly further and easier.
4. Decorate!! We named ours the 'Rat Rocket' and have various designs on it.
5. Create a funnel out of paper or take an actual funnel, this will be used to funnel the baking soda into the bottle.
6. Take the bottle outside and get ready to fly it. Fill the bottle with vinegar, not too much to outbalance the baking soda though. Make sure there are other people around to help you with the next steps. Have someone stand by with the cork.
7. Pour the baking soda into the bottle through the funnel and quickly put the cork in the bottle tightly and stand it on the pencils.
8. FIRE IN THE HOLE!!!

Not even close to our rocket but was an inspiration and basis
