Place in a bottle of oxygen gas a lighted taper, and it will burn with
a flame of increased brilliancy.
Extinguish the taper immediately; put it into the same or another
bottle of oxygen, and it will be again lighted provided a spark remain
on the wick.
Bend a piece of iron wire in a spiral form, and tie on to one end some
cotton or flax; sprinkle some flour of sulphur on it, set it on fire,
dip it into a bottle of oxygen gas, and beautiful corruscations will be
thrown off the wire.
