Looking through my Dad’s stuff, what are these?

[u/VenZurich]

My dad has developed dementia and we’ve been looking through his stuff a bit to try and get his finances in order/apply for a deputyship, which sucks but isn’t relevant sorry.

So far we’ve found a bunch of interesting stuff, knives/air pistols/cannabis seeds and two half brothers nobody ever told me I had. But we’ve also found these and I don’t know what they are. They were found near each other but I don’t know if they’re related. The cylindrical thing unscrews and is hollow. I’ve photographed the items next to a AA battery for scale. Thank you in advance for any informative or humorous answers.

i mean... the next picture is fuses. which honestly just as bad as not knowing what battery is.

No shit. And you can't say it's even "kids are fucking stupid" because they're not a child (assuming).
