You're not an idiot!!! Most of the bite valves come closed. You have to work on them a bit to get them open. If you just bite and suck, the valve may still be shut, and you'll get nothing. Try squeezing and manipulating the valve a bit with your fingers or teeth.Make sure you can squeeze the valve and see that there's a hole there!he directions on the packaging are kind of deceiving. You need to pull open the valve and then press the bite valve open with your thumb and finger. It took a few times but mine finally popped open and works!
