Is tubing used in fish tank air pumps "food quality" tubing, like a drinking straw?
I'm wanting to use some (new) plastic tubing that is used with fish tank aquarium air pumps as a drinking straw but I don't know if it is safe "food quility" plastic.
How about the plastic tubing used for oxygen machines? Is that safe to use for a drinking straw?
I'm trying to make a cheap hydration system to use while kayaking so it keeps my hands free to paddle.
