Welcome to our list of things that float! 🎈🪂˚ ༘ ೀ⋆｡˚

Floatiness describes the ability or sensation of being buoyant and light, often associated with objects or materials that can effortlessly stay afloat on water or drift through the air. In textiles, floatiness is often used to describe fabrics that are airy, light, and drape gracefully, such as chiffon or silk. In a broader sense, floatiness can also refer to a feeling of weightlessness or ease, often experienced in activities like swimming or when feeling particularly carefree and unburdened. This quality is valued in various designs, from fashion to engineering, for its aesthetic appeal and functional benefits.

Here’s a gallery of floaty things, followed by a categorised and informative list:

Food

The ability of food to float often depends on its density, composition, and sometimes the way it’s prepared. Foods that float are usually less dense than the liquid they are in or have air incorporated into them. Here’s a list of foods known for their ability to float, along with explanations for this characteristic:

Apples: Due to their air pockets and less dense structure, apples float in water.
Puffed Cereals: These cereals are processed in a way that incorporates air, making them light enough to float on milk.
Marshmallows: The air whipped into marshmallows makes them light and buoyant.
Popcorn: When popped, popcorn has air inside, reducing its density and allowing it to float.
Ice Cream: Most types of ice cream float in sodas and other liquids because of the air incorporated during the freezing process.
Meringues: Made by whipping egg whites with sugar, the air trapped in the mixture makes meringues float.
Oil Droplets: Most types of cooking oil are less dense than water, causing them to float.
Bread: Especially pieces of light, airy bread, they tend to float on the surface of soups or stews.
