Siphon Bath Toy (STEM)

My kids found the idea of a siphon amazing during bath time.  So I made a simple siphon plunger system for them to be able to do it on their own without using their mouths.

The print is pretty simple and fast.  No supports needed depending on how you scale it (i did 70% on my Ender 3).

Enjoy and let me know if you have any ideas to make it better :D
