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!)

Or fill the tube with ~3 cm of water before taping the end shut.
That's entirely too practical. That's never the correct solution to a physics problem.
true on both counts:agree:
i do wonder about the 3cm though. i would be taking in a lot of water if mine were that low.
