How does pressure equalization work in this mask? I've been thinking for a long time but I still have not invented.
Noni! The mask has a kind of nose clip with balloons on both sides. Let's test the with a mask for pressure equalization in two different ways, and before you go to the depths, try your favorite way on the surface. Under the surface, it's a little harder to fix ...
- between the nose balls so that you can use them to close the nose and blow towards the nose
- If you use bigger balls in it, then they can visit your nostrils so that you get your nostrils pressed against the bigger balls and blow them bvasten ears open :)
Come visit as you will be guided if you so desire.
