Universe Unboxed: Is it a good deal?

Good Will has a listing for Universe Unboxed Survival Science., which lists for $20.  The contents and experiments look interesting.  FYI Calcium chloride is Driveway Heat.  The iron filings are to make a hand warmer.  The projects include a compass,solar oven, and filtration system.  It has an assortment of experiments.  The listing comes with a game, True Science.  This is the sort of kit I buy for gifts.  You might want the kit for the experiments.  I do buy kits occasionally to see the contents and ideas for experiments.   Not a bad deal.
