Not to be outdone by Team Numb’s Beer Keg launch, I improvised with what I had in the desert, and sent my son’s milk bottle up in his Nike Smoke rocket on a K550… and got it 100 ft. higher (6,258 ft. per the onboard HCX flight computer).

I was racing Erik’s GLR Vertical Assault flying on one of my favorite motors, a CTI L730 which burns a thermoplastic propellant from a Canadian aerospace company. He just rips off the pad and out of the frame, and disappeared into the sky (with blue “camo” paint)…

Launch Video

I cut a few minutes of mystery from the middle of the video as we were looking up in the sky for our rockets. We both packed orange chutes and only one orange chute was visible in the sky… Who’s rocket was it, and where did the other one go?

Both rockets were recovered in perfect shape. (my chute was in sight, and Erik’s was discovered several hours later by others). I shared the rocket milk with Team Numb as they were having cookies on Sunday. The motor warmed the milk to body temperature… just like mama used to make…

  1. I forgot to mention this was the maiden flight for my son’s first high-power build. We used four Jenga blocks vertically on the inside to couple the thrust from the bottom motor bulkhead to the bottom of the four fins. It was a perfect fit.

  2. Oh sure…. it holds the motor in. =)

    and expanding foam too.

  3. THanks Steve…In spite of what Rockets Magazine says, the Vertical Assault is clearly loooong gone, while your milk rocket is still straining off of the launch pad. =)

    Wait a minute!

  4. I am on the road with phone, but your shot looks aweosme on the crackberry. The accidental motor test in the foreground is priceless.

    Remember my nosecone was jammed against the rail… Next time I’ll be slip sliding away.

    Glad you saw the Rocket article. I can imagine the audible chortle…
