Fired and unfired pistol, rifle and shotgun ammo. I think I could give an interesting talk on the differences and the history of various cartridges, no fine details, only a broad overview. To keep it fun, I'd sprinkle in lots of things most people probably don't know.

For example, did you know an AR-15 round is actually kinda wimpy, especially compared to a typical hunting round? In some states, ARs are illegal to hunt with because the bullet is deemed too small to make a clean kill. It's basically a hauling ass .22.

And .22s are a neat topic by themselves. There's crazy variety out there, even tracers!

My fully water cooled itx PC running arch, then I can force my hubby on them 😍

I'd bring my Moog Theramini. Nothing like playing the air waves! It's magic science!

Probably a synthesizer. MEGAfm would be the coolest, but I imagine my desktop Hydrasynth would be more impressive.

Not sure what a show and tell is, I guess my laptop with tons of stickers, and boot up something that looks hackery. Besides that, my guitar perhaps?

I'd bring some beer that I make in my garage.

My knives, because it's sort of weird even for me that I carry these knives around for work, and a weird thing becoming humdrum is the sort of thing I'd like to hear about at the show & tell.

Climbing gear or 3d printers.

My autograph collection.

Probably either a Ken Payne bronze called The Trail of Change or my Ibanez s521 guitar with the ocean fade paint job.

Inherited it from a family member who loved southwestern and native American culture and history they shared with me so it's some sentiment along with an interesting statue.

Most of what I own is minimal and function over form but I just think it looks awesome and is fun

Professional level landscaping accessories.

Folks always seem fascinated by my keyring.

My papercrafts.

Depends, is it a casual thing or more serious? If it's casual I'd probably just bring a Trading Card Game deck (MTG, YuGiOh, Pokémon). If it's more serious, I'd bring in some of my junk like a broken microwave magnetron, to simultaneously bring attention to the problem of short product cycles, explain a bit about how what most people see as a magic appliance functions, and show that even complex things can be broken down into simple parts.

You know, I think an adult show and tell wouldn't be too different to a kids one, we don't change that much in what we find cool from 7 to 70.

I'd bring some pets, I have geckos that are an all female species and reproduce only through parthenogenesis, most people find them cool.

Beer. Not to show, just to enjoy it.
