Twisting Fountain – A Fun and Educational Water Gadget / Toy / Fidget

Experience the magic of water flow with the Twisting Fountain!
 
This 3D printed gadget turns a simple motion into a playful mini fountain.

 

How it works:
1️⃣ Fill in water on Side A
2️⃣ Rotate the model
3️⃣ Now the water flow through the internal channel and create a fountain effect on the another Side B (see pictures & GIF) 🌊

✅ Educational & Fun – a simple way to demonstrate principles of water flow and pressure.
✅ Easy to use – just add water, twist, and enjoy.
✅ Relaxing & Engaging – perfect as a calming toy or playful desktop gadget.
✅ Optimized for 3D printing – easy to print, no supports needed. (print in place)

Whether for science exploration, playful experiments in school, or just a relaxing distraction – the Twisting Fountain is a unique addition to your 3D-printed collection.

🔬 Physics behind it:
Water is filled in on one side of the model and then the whole piece is rotated. The water flows through the inner channel, accelerates due to the continuity equation and the Bernoulli principle, and finally reaches a narrowing at the outlet. This nozzle effect forces the water to speed up and exit as a small fountain jet.
