Done, as in personally done?

Sodium in water, methanol + dissolved salts (Emission spectrum, as a demo for my students). I also LOVE using Brady's reagent (2,4-DNPH) to detect carbonyl groups. And the classic elephant toothpaste! :D

Seen?

Decomposition of Mercury Thiocyanate, Barking Dog, Sodium + Chlorine gas, etc... too many!

one of my favourites is 'thunderstorm in a bottle' e.g https://www.youtube.com/watch?v=Nyzlt-dVgWQ

easy to do and impressive for a small audience (family, friends etc.)

add a little of the permanganate at a time
use methylated/de-natured alcohol, acetone is too violent.

using the bottom 1/4 of a conical flask reduces splashing.

I once made my friend eat a banana and drink a big ol' sprite. I'd recommend that one for sure. Before you do it yourself, first give your little siblings the opportunity to make a coin, and also so you see what it'll be like.
