Have you already run your Jerry through all the mazes provided by the Jerry Base Kit? Get more out of your slime mold with this Expansion Pack! This kit includes: - 5 petri dishes, - Agar to fill the petri dishes, - 2 unique mazes, - Tweezers (not pictured), - 2 packs of sterile swabs, - pipettes. This is a PRE-ORDER, expect at least 2 months delay as we gauge demand and maybe a bit more time for Jerry to grow should we receive more orders than expected.
