Hand-free video watching
Speaking of holding stuff, check out this cellphone holder. This is a phenomenal idea because, with one of these, one doesn’t need to have the phone in their hands while watching a video, especially if it’s a long one. Do you think it would work in the pool too?
All that you need is a round piece of noodle in which you should make two V-shaped cavities, one perpendicular to the other: one will be where the phone is placed, and the other will allow you to move your finger through it. Nice, huh?
