Rain and hail will be suspended by the updraft inside a thunderstorm until the weight of the hail and water can no longer by supported. Usually, the stronger the updraft in a thunderstorm, the more intense the storm and the larger size of hail that can be produced. Suspending a ping pong ball in th estream of air supplied by a hair dryer will demonstrate how hail is supported in thunderstorms.
