Fun & Games Photography & Video

Cobbler from Portland, OR, built a water rocket and added video, capturing how awesomely his rocket flew, as well as renewing the adoration of his daughter!

I built the Water Rocket project from vol. 5, made a few small modifications, and shot a video including aerial footage from the on-board camera. Of course, I opted for the increased speed and pressure of an air compressor running at 150 PSI instead of the hand-operated bike pump.

  1. I would hate this guy as a neighbor. I don’t need junk hitting my house, trees, etc. Go to a place with more room like a park! Sorry, I realize I’ve become the cranky “get off my lawn” guy.

    1. Yeah, he’s renewing the adoration of his daughter and the enmity of his neighbors.

      I hate to put a damper on anyone’s creativity or adventures with their children (and he gets bonus points for attaching the camera to the bottle), but there is a time and place for everything and the cul-de-sac of your quiet little suburb might not be it for a water rocket.

      Easy for me to say that, of course, having a park directly across the street where my daughter and I go to explode things.

  2. I still want to stress that using plastic pipe for air is easy but not the safest idea. This stuff can fail rather catastrophically and send flying pipe into anyone or anything around. A typical two-liter bottle can generally reach the 100 psi without failure. But even at 100psi you need  to make sure you know what is going to happen to the bottle when it eventually ruptures after continuous reuse. Just a few tips. Be safe and have fun.

  3. Kudos to your nice project! I use a similar setup for science outreach at my University. Let me caution you against pressurizing soda bottles to 150 PSI, as mentioned in your video. While I’ve never had a problem with Schedule 40 PVC breaking on me, Soda bottles begin to unpredictably fail at about the 110 PSI mark (This varies on the make, how many times they have been used, and exposure to sun). While I doubt you would hurt anyone, the possibility of getting a shard of thin plastic in your eye is very real (not to mention scaring the bejeezers out of your daughter with the blast).

    Stay safe and have fun!
