Making the World's Deadliest Popsicle

Something that I've always wanted to do, turns bromine into a popsicle. To do this, I'll use a glass rod for the stick. Then after that, I'll put a small Dewar flask under it, and fill it with some nice and cold liquid nitrogen. As it sits there the bromine should slowly
freeze, because its freezing point, is only about negative 7 Celsius, or 19 Fahrenheit.
The liquid nitrogen is way lower than that at around negative 196 Celsius, or negative 320
Fahrenheit.
