Liquid nitrogen is used in a wide variety of applications. In particular, it's used in superconducting magnets, which means that Florida would be an incredibly stupid place to locate the National High Magnetic Field Laboratory if liquid nitrogen were illegal there. Want to guess where the National High Magnetic Field Laboratory is? Yes, liquid nitrogen is legal in Florida.
Equipment in a lab is in a protected environment so that experiments can be done that might not be safe in other circumstances. In addition, you can control more factors (ie. temperature, light, movement) when running an experiment in response to a hypothesis.
