sandless sandbags

Peyton Robertson is 11 years old and since he was 3, he's been solving math problems.  When he was 4, Hurricane Wilma struck while he and his father huddled together in a closet.  Peyton combined his fear of hurricanes and his love for math to come up with a possible life and property saving sandless bag.  They're filled with the right amount of ultra-fluid polymer that only weighs a couple pounds when dry but when wet, won't float away because thee chemicals expand and become very heavy.  sandless sandbag
