Api leaky tube solution!?

[Angellove78]

Been reading alot of posts that say their API test tubes leak. So thought I'd post another one of my so called "great ideas". Hope this helps everyone. The cap does not have a rubber seal inside. If you have a o ring small enough or a small rubber band take some tweezers put the rubber band/o ring around them and slide it around the seal part. I used a baby rubber band for my daughter's hair I had. Pics:

Great idea. Another good idea would be the rubber bands used for braces.
