Found in bathroom after grandma left.
Thin glass with a dried residue over it. No smell and its like a think film over the glass thats stuck to the curved inside part. Im pretty sure I know what this could be. I need other opinions from the professionals of reddit.
Edit: its not a contact lense, not sure why people skip the description so this probroly won't be seen. I basically need confirmation for something im pretty sure of what it is. Grandma is not a normal grandma and this will probroly lead to no contact if its what I think it it. She wears glasses and shes always made questionable choices.
Final edit: majority went with what I already suspected. Broken meth pipe, im going to try and brun a little residue and see how it reacts for a confirmation. I appriciate all the people willing to help with my silly questions. Im pretty lame to all this stuff.
