Help bubbler become hydrator! pics

Hey, Im tired of holding the tube to my bubbler bowl... And I was wondering if you guys could help me make a contraption to hold the tube in the bubbler bowl. Kinda like an easy plug-in/unplug.

I was thinking of creating a cone with a hole(for vapo tube) in it. Then just insert tube in or remove.
But what material should i use? Or any other ideas? Thx!

Hey there. Try using a mini rubber-stopper (rubber cork/plug). You can get ones with small holes through the center.
