Black powder rocket lifting sand bag

Huppscustom
#3 size
This is a test what i call "Sand Lift Test"
I do these test so I know how heavy a header I can put on top and to what height. Helps adjust the delay properly as well.
The Salute at the end is just so I know when the delay ended. Just a visual aid in the test. It also shatters the sand bag so no one gets hurt or property damage happens.
