On April 12, 2019, we will have our monthly Pack meeting at Ellsworth Hill gym/cafeteria. We are excited to try a new Pack activity at this meeting – Scouts and siblings will launch (using water pressure) rockets that they have made from two-liter carbonated bottles (assembled at home prior to the meeting). See below for assembling guidelines and tips.
Scouts should wear their Class As withOUT neckerchiefs (we will be launching rockets outside, and I want to minimize lost neckerchief slides). As usual, the Pack meeting will begin promptly at 7:00, with gathering activities beginning at 6:45. The Webelos I will present the colors. Upon arrival, and before the 7:00 start, each Scout (and sibling) should enter his/her guess for monthly guessing game.
A few notes about building the rocket:
- Water bottle rockets can be constructed in an hour or less at home using supplies you probably already have. Please have fun with it and include your Scout in the construction. There are tips online (e.g., these basic stability tips) on how to make the rockets go higher and farther, if you want to devote extra time. A good place to start is this YouTube video. Your Scout should feel free to decorate his or her rocket as your Scout sees fit, but, AT A MINIMUM, should include your Scout’s name on the rocket to distinguish it from others.
- Arrive at the Pack meeting with your Scout’s (and sibling’s) rockets already built and ready to fly.
- The bottles used to construct your children’s rockets should be carbonated two-liter bottles (carbonated bottles are stronger, which will allow the bottles to retain more pressure prior to launch and fly higher).
- Know the construction limitations regarding the rocket’s fins. Because of the way our rocket launchers are constructed, fins that dip below a certain point will prohibit the rocket from sitting properly on the launcher. Consult this schematic for fin placement. Basically, make sure there is at least 0.75 inches between the bottom of the fin and the disc of plastic that encompasses the two-liter bottle’s spout. There will be a launcher at the meeting where you can test your rocket’s fit. If the fins are made of cardboard (as is recommended) a few snips from scissors or cuts from a knife should remedy any problems.
