A tiny container of “explosive” liquid like that would barely do any damage in the trashcan. Worst case it would injure a few people.
The same explosion at 30,000 in the plane would be catastrophic.
I get TSA is a lot of bullshit, but there is no really good solution for this except some hyper rapid liquid tester.
Which just isn’t worth it dump it out and refill it past the gate.
I really wish we could have a license like if your revenue is 5mil + you have to kick in something to the devs
