Try and launch your bottle as high as you can. Can you get it to break the earths atmosphere.
Press the Launch button to enter launch mode. The bottle rocket will fill with water. Click the Mouse to stop the bottle filling. Now a count down will appear above the bike pump. You have until the clock runs out to fill your bottle with as much air as possible. To fill simply click and drag the Pump Handle up and down, just like a real Pump. The more air and water you put in the higher your bottle will go. Once the Rocket is in the air guide it through the air by moving the mouse left or right(the mouse must be higher than the bottle). Avoid hitting clouds, and pick up the bonus to go even higher. Goods Luck!
