Another use for plastic bottles

Baby Soda Bottles: These are made from the pre blown plastic bottles that are for water or soft drink. You can see what I am talking about in this old post.

These are good for storing just about anything small you don’t want crushed, spilled, or dampened: Batteries, earbud headphones, mini-first aid kit, medicine.

The ones I liberated from my son’s Scientific Explorer kit are also sold individually as Tube Vaults by County Comm, but the best deal I’ve found is 15 for $10 from Steve Spangler Science. According to their site, the Baby Soda Bottles are actually our ubiquitous 2-liter soda bottles before they’ve been heated and stretched, which explains why the caps are interchangeable with soda bottle caps.

These food-grade polyethylene test tubes are dishwasher safe, strong, waterproof and, yes, I’ve used one to hide a geocache!
