While I am smarter than a five year old (me thinks so), I am struggling with fitting 1/4" vinyl tubing on the barb of a diffusion stone.
I've tried soaking the tube in warm water, soap, force, swearing, and sweet-talk but the best I can do is push the tube two barbs up on a 6 barb post.
I have even heated the tubing, shoved a tapered metal chopstick an inch into the tube, cooled the tube in the freezer (with chopstick) in hopes that the tube will maintain form. Nope. Do I need to boil the damned thing to make it more malleable?
Can you help me outsmart this tube?
It appears to be easy but this freaking tube is defeating me.
