Paramagnetic Oxygen

In a candle cup is liquid nitrogen, beside it a stron NeoDym magnet. On the cup condensates Oxygen, the drops are attracted by a strong magnet. The flashing flame shows, that the drops are Oxygen, the attraction shows the paramagnetic behaviour.
The boiling temperature of Oxygen is about 90 K - a bit higher than liquid Nitrogen (77 K). So Oxygen condensates more than Nitrogen.

It is not that easy. IN the cup is liquid nitrogen. On the outside liquid is condensing, this could also be water (from the air). The flashing fire shows, that it must be liquid oxigen and not water.

Liquid oxygen is magnetic and is attracted to the magnet, it drips out of the cup and falls to the left because the magnet is pulling it, the fire is there for no reason probably

confused!

@cacharucha there is liquid oxygen dripping onto the magnet and into the flame
