Goat Simulator Itsamee! Achievement

Goat Simulator Itsamee! Achievement
Use a cannon to travel to the Island in the Sky.
The cannon that you need to use is on a hill with the radio tower which overlooks the stadium. Walk up to the cannon and press to enter it. Aim the cannon so the whole island is visible, but the bottom is just barely visible. Wait for the strength meter to be about three-quarters full then press to shoot yourself off. As long as you touch the island (you can fall short or overshoot it), the achievement will unlock.
