Hydro flasks are great for keeping drinks cold and hydrated on long flights. But did you know that some models actually explode?

The problem stems from the design of the cap. When it's removed, there's a small gap where air can enter. If you're drinking something hot like coffee, tea, or soup, the pressure inside the bottle could build up enough force to cause the lid to pop off.

This happened to one passenger on a recent Delta Air Lines flight. Don't worry about your flask exploding on a plane. You'll never see it happen. But you might want to avoid drinking anything hot while flying.
