Fun With Rockets

Derek and his friends decided to have a liter bottle rocket launch competition

Working on the launcher

Making a trophy for the person with the highest launch

About 40 psi

Lift off

Blake wins the trophy (6 seconds in the air - about 60 ft)

Birthday Girl

Helen decided she wanted a carrot cake for her birthday



It would have been nice if we boys could have pulled it off by ourselves, but we needed the birthday girl to help us

Some appetizers before dinner

Derek was very pleased with Helen's entrée choice

Yum

Derek says now that he has a 3D printer that we'll all be getting 3D printed trinkets as gifts
