One of the most magical and purely amazing experiences of my life was when I snorkeled for the first time in Cozumel, Mexico. I actually cried tears of amazement and joy for a brief moment when I first experienced the beauty of the ocean. I was mesmerized! I can see how people would have a hard time with the snorkel mask and breathing tube as it is. It took me a few tries before I really got it to work right also. THIS changes everything! Anyone could use this. I hope to maybe get one myself one day for an even more comfortable experience in the ocean. I've never tried this, just witnessed the video and ended up saying "Wow" so I thought I'd share it with you!
