We each then wrote a local fact on to a piece of card that also had a QR code on it with our blog address and contact details so that people can reply to us, and released these 'messages' attached to helium balloons.
It was so exciting! It was a very still day so we could see the balloons go up, up, UP!
We used a compass to see which direction the balloons had traveled and then predicted where the messages may end up by looking on a map. The balloons went East, so we think we might get replies from Lincolnshire, Scandinavia or even Russia!
