Virtual Balloon Race
Each balloon costs just £3 and you can buy as many balloons as you want to increase your chances of winning.
It's a seven day computer simulation race where everything is real except the balloon.
The software designed to run the race uses live weather data to determine the progress of each balloon and each entry can be tracked on Google Maps and Satellites once launched!
You can buy a virtual balloon for £3 and give it a name, colour, shape and pattern.
The "School's Out" race will set off from Hogwarts School on 3rd July and you can join the race by clicking on the button below.
