Check out SMR ground testing the ejection charges on his recycling container Jayhawk, the JayCoke Zero. You can read all about the build here (direct link to the page showing the full view, with the Coke decal, see post #119). While on the subjects of Jayhawks, SMR has a whole fleet one them, from LPR to HPR. He's my kind of rocketeer - he also made them from crayon coin bands and various plastic doohickies. You can see his fleet, along with other people's Jayhawks, here (see post #8 for SMR's fleet).
Update: The flight report can be found here.
