Tornado

A huge funnel awaits you on tires for 2 or 4 people. Then it goes first leisurely and then faster and faster down until you have reached the funnel and then sinks in it. You then swing out before the funnel swallows you completely and then spits you out on the other side.

Hints:
Height restriction: from 1,22m
Weight limit: up to 317kg per 4 tires
