SARSEF Science Fair - Brenda's Fat Daddy

Brenda's entry into SSA Broadway's science fair for SARSEF. She did great and barely missed going down to the Tucson Community Center. Her display was a favorite among some though, especially when she had so much fun telling people why she named the heavier one, her "Fat Daddy."

She compared flight altitudes of a standard Estes Big Daddy rocket with those of her modified version of the same rocket that she joyously calls "Fat Daddy." She predicted the one that weighed more would not go as high when flown on a motor of the same power (total impulse). She was right! The additional weight of the X-10 wireless camera and 9 volt battery would definitely take some more juice to get it up to the same altitude.
