The story of Sip Tube Backpack
The Sip Tube Backpack made every kid feel like an astronaut on a mission. A rubbery tube snaked over your shoulder and clipped to your strap, and biting the valve squirted water into your mouth. Kids drank the whole thing before the bus left the school lot, then spent the field trip chewing the empty valve.
Fun fact
Some kids filled theirs with juice instead of water, which turned the tube sticky and the backpack into a science experiment.
