If you do not wish to sign up for the subscription service, go to SteveSpanglerScience.com and click on STORE. Then click on STEM in a Box. These are the only kits we currently offer as one-time, non-subscription kits.
STEM in a Box kits will ship immediately via the method that you choose and not be shipped once a month like the regular subscription kits. The best part is you can pick the kit you want!
