This is a Volcano with base for the Vinegar and Baking soda and dish soap experiment, I have included holes for TPU printable feet and Plug for the bottom (10-15% infill, recommend raft for TPU feet) . For the volcano, I printed it on the Bambu Lab X1 with AMS unit 15% infill in chocolate and Bone white PLA, If so equipped, you could use blue for sea effect. (I would use paintable supports for foot-holes in model only, supports not needed for Volcano model) I have remixed a funnel model from Boogie to be right size to add vinegar/dish soap/food dye to your Baking Soda (PLA with 20% infill for funnel).
