This is a very cheap, very simple water bottle holder that can be placed on a bike to provide easy access to a drink of water on a long, summer ride. It only takes about ten minutes to make, and actually recycles things that probably would have otherwise been thrown away (namely the tape rolls and the ties).
Step 1: Materialz
You will need:
Three (3) empty duct tape/packing tape rolls
Grey duct tape
12 Ties from produce section of grocery store (pssst its not stealing! Its permanently BORROWING! Jk. Maybe just save the ones from the fruits you buy)
