BackyardScientist demonstrates how to create a hoverboard using dry ice. The project involves using a piece of wood with a lip to hold dry ice blocks, creating a frictionless surface. The video covers the construction process, testing, and challenges faced, such as slipperiness. It also explains the properties of dry ice and the need for a large space to enjoy the hoverboard. The project is simple and fun, with the hardest part being finding enough space to use it.
