Hello all, first-time poster here, with a time-sensitive question about taking flasks (2) in a carry-on bag on a USA domestic flight. We're talking about ~15 ounce sealed plastic/glass flasks with seedlings and of course agar. If anyone can share recent experiences about whether these go through TSA security or not, I'll be grateful. I want to deflask in advance if necessary! Thank you!
I would suggest keeping them in a carry-on that can be easily opened for inspection. As there are no liquids more than 3 ounces per unit, it should be no issue.
In fact, I suspect anyone asking about them will be fascinated....
