a large vehicle that is decorated to drive through the streets as part of a special event:
We stood and watched the Carnival floats drive past.
a sweet drink that has ice cream floating in it
a small light object that floats on the surface of the water, used by people trying to catch fish to show where their line is
a flat light object that you can rest part of your body on in water to help you learn to swim
a small amount of money that someone in a shop keeps so that they have enough money to give change to people
a time when shares in a company are made available for people to buy for the first time [= flotation]
a time when you sit in a flotation tank in order to treat illness or injury, or to relax
