A group of beaver and cub scouts had a very special camping trip on the weekend - in the garden of 10 Downing Street!
15 boys and girls pitched their tents on the Prime Minister's lawn to raise money for kids' charity Sparks.
The group from south London had a tour of David Cameron's home, cooked dinner and played games before settling down to bed.
Everyone also got a special badge with the front door of Number 10 on it!
Prime Minister David Cameron is on holiday at the moment.
