What's inside those liquid filled hourglasses?
You know those acrylic liquid hourglasses?

I wonder what liquid composition that's inside them?
Can't be oil and water... The oil would rise instead of drop.
Can't be oil and alcohol either... the alcohol would break up the oil's olester strings.

they don't mix, they don't emulsify, they have a high tension surface ratio (hence the cute little balls and the non-stick to the recipient) and it seems they are rather stable since I own one that is about 25 years old and still works (the level has dropped though. )

Does anyone know what it is?

Water with coloring and mineral oil; same as wave tanks.

It's the colored water that is falling in drops.

so here... the oil is really thin, It's viscosity matching that, or even below, that of water?

It's not viscosity, it's density. The mineral oil is less dense than water.

The water has coloring added so the drops of water falling down through the mineral oil are visible.

I'm not saying that because there is a gag order.
