I Found a Bag Full of Strange Glass Tubes in My Uncle’s Room — You Won’t Believe What They Might Be!

The first rule when dealing with unknown glass tubes is safety:

• Always wear gloves to prevent cuts or contact with unknown residues.

• Do not taste or smell the contents. Some residues could be toxic.

• Handle the tubes gently — glass can be fragile and brittle.

Even if they look harmless, it’s better to err on the side of caution.
