Tornado

Tap to spin it up. Set its power in the Splash tab.

A tornado is a spinning column of air that reaches down from a thunderstorm to the ground. It is the most violent kind of storm on Earth: its winds can blow faster than 400 kilometers an hour, though most tornadoes are much weaker and last only a few minutes. The United States has more tornadoes than any other country, about 1,200 a year.

Tap it to spin it up: the funnel widens and whirls faster, dust boils up at its foot, and the planks, clods and leaves on the field are lifted one by one, spiral up around it, then fall back where they lay as it weakens. The Power slider in the Splash tab sets how hard it swirls.

Made in Splashery. Its code is MIT.
