I have a few spare glass bottles and want to explore what decoration I can make with them, without just painting outside them.

Preferably safe, in case of an accidental breakage or leak. Preferably indefinite shelf-life.

Some ideas:

Density layering experiments ('rainbow in a jar', maybe suspending an upside-down toy boat in a dense clear liquid with a blue watery liquid on-top)
Phosphorescent liquids to glow in the dark (pref with no UV lamp needed)
The oil+water+antacid+food coloring lava lamp, but the effect is probably too short-lasting to have running for a few hours

My kids made tgat for mothersday once. Looks actually nice. It's still on display after 5 years or so

Ferrofluid for sure

The proper stuff is expensive (~$1USD/ml), NileRed's recipe is 2chem4me, but the cheaper ferrous suspension methods might be workable...

Tempted to try the Traffic Light Reactuon, but I don't know how safe it is to store something that alkaline in a regular glass bottle long-term

Sulphuric acid

following on from an earlier comment in anothe thread, nitrated organic compounds come to mind, Toluene or Glycine.

The story I shared (or maybe some other online chat) may have got me on a watch list post the events of September 2001, so use at your own discretion.

Have you considered Spiegel im Spiegel.

Do you mean an infinite mirror, like this?
