An event in London this week is aiming high to set a new world record.
For the first time ever, 25 aerial gymnastic performers will perform a synchronised routine at a height of seven meters.
It’s all part of the anniversary celebrations for the construction company Mace - who built the Shard and the London Eye.
We caught up with them during their rehersal.
Danielle Dickinson is from Mace, the international consultancy and construction company putting on the stunt to celebrate it's 25th anniversairy.
