Goatalanche

High in the Alps there lived a simple goat farmer. The farmer had the best goats for miles around. However, his goats had one fatal flaw. They couldn't climb mountains. This is a big problem considering they live in the alps. The farmer did what any reasonable man would do and went and got a trampoline to bounce his goats back into the air so they won't hit the ground. Help the farmer move his trampoline back and forth to keep his goats bouncing. Slide your finger back and forth to control the goat farmers and their trampoline. Position the trampoline under the goats to make them bounce upwards. How long can you keep your goats airborne?
