Folly Beach

3 days ago we (my Mom' me and my sister) went to folly beach and collected 15 shells and my sister got bivalves (a two part shell encloses around a creature). The bivalves matched. My sister got them to stick and  I  put them on display in my room. The tide wave markings in the sand were really high' roughly 15 feet. We also found a tide pool. We washed all our shells in the tide pool.
