DIY CO2 Drop Checker

So here's my attempt at making my own drop checker. Tried my best o take step by step photos after the project was compete. Takes about 10 minute to make. Hope this helps someone out.

What I used:

Cap from a nasal spray
Travel bottle of hand sanitizer
Aquarium sealer

-Cut the top off of the hand sanitizer bottle

-Drilled a hole in the nasal spray cap

-Slide the nasal spray cap into the hand sanitizer opening (narrow end in first)

-Make sure every thing is clean, seal it up, let it cure, and your set to go.

I'm going to pick up the solution tomorrow and test it out. But here are some shots with it filled with a little bit of water.

You can't really tell, but the drop checker is being held in the tank.
