Amazon is offering the Thames & Kosmos Ooze Labs for $17.90 Prime shipped. For comparison, it normally goes for $30 and today’s deal marks a new all-time low. If you’re looking for a great and fun way to teach your kids about chemistry, this is a fantastic option. There are four different kinds of slime available here and it’s paired with a ‘fun, fictional storyline’ where you’re the lead chemist in your own ‘out-of-this-world laboratory.’ You’ll be conducting viscosity tests, dissecting it, and cutting out a brain shape, plus much more here. Plus, all of the materials are non-toxic and contain no borax. Rated 4.3/5 stars.
