Ever wonder how to prolong your beautiful jack-o-lantern from becoming a pile of mush? My Science Project has taken a fascinating look at common remedies for pumpkin preservation and found that applying bleach and Pumpkin Fresh are the two best means for preservation, but that applying nothing to the pumpkin can also be a safe option. I only wish they tried WD-40, which was suggested by Extreme Pumpkin master Tom Nardone.
