How many pennies I should duct tape to my swim snorkel to counter the buoyancy created by the air in the snorkel’s tube?
I was experimenting with using the snorkel today and found the upward pressure it placed on my forehead (where the snorkel strap meets my head) unpleasant. I wondered if somehow weighting the snorkel would help, and came up with the plan of taping pennies to it.
But how many? I have noticed that there are a number of physics-savvy people on the forums, and wondered if someone could figure this out.
It’s a Finis Freestyle snorkel. The volume of the tube varies—there’s about 22cm of tubing that is round, with a diameter of about 2cm, and an additional 32cm of tubing that is a rounded rectangular shape (around 3 x 1 cm). About 3 cm of the latter section is above the water when I swim.
So can anyone help me with this? My purple plaid duct tape is at the ready.
(And if anyone has any better ideas for fixes, involving either snorkel or swimming technique modifications, I’d love to hear them!)

Interesting. My biggest physics problem with my Finis snorkle (non-freestyle version) is that the purge valve points towards my feet. Therefore, the only way it purges is if I lift my head really high. That's the only way that the purge valve is the lowest point.
So, I'm limited to open turns.
Any suggestions on how to correct this? Perhaps I should just tape over the purge valve with multi-colored duct tape, and blow the water out the old-fashioned way.
