After recently getting a new cage for my 2 budgies (that was clearly massive for them), i decided they needed a new food and water bowl because the ones they had in their other cages didnt fit in the new one. I saw some on the internet that were $10 each and didnt want to wait 2 weeks for them to arrive. So instead i gathered some supplies and got to work.
Step 1: Gather Materials
Pocket knife or scissors,
1x small bolt (about 2cm),
1x small nut (to fit bolt),
1x small wing nut (to fit bolt),
1x 1.25L empty soft drink bottle.
