About

Andy Hancock teaches science-based sandcastle building as a family STEM experience on South Padre Island, Texas. This channel shows a verified, step-by-step system for building strong, stable sandcastles using applied science. You’ll learn how sand behaves under forming, compaction, gravity, vibration, and professional tool use—so families of all ages can succeed on any beach. Sandcastle Lessons turns a day at the beach into hands-on STEM learning. Videos include full how-to lessons, tool demonstrations, sand testing, and real builds taught directly on the beach.
