By Michael Merry. Whether an object sinks or floats depends on the density of the object and the fluid in which it is immersed. An object that is denser than a fluid will sink in the fluid while an object that is less dense will float. A floating object is said to be buoyant. The classical Greek inventor Archimedes was first to understand that ...Web

All liquids and gases in the presence of gravity exert an upward force—called buoyancy —on any object immersed in them. If the object is less dense than the liquid or gas, buoyancy will make it float. A cork floats in water because it is less dense than a cork-size volume of water. But it won't float in air because it is denser than the ...Web

Snow can be slippery. After flotation, traction is the most important snowshoe metric. After all, flotation with no traction is what skis are for. While the traction on the Helium Trail isn't bad overall, we had higher expectations. Side-by-side testing with similar one-piece plastic snowshoes showed this model slipping slightly more often.Web

1. As I understand, in a balloon/air balloon, a gas burner is used to heat air or using some lighter atom like helium. Since helium or hot air is lighter and less dense than the cool air around the balloon, the heated air or helium causes the whole balloon to rise. And as I understand, vacuum is a space where there are no atoms inside.Web
