can you guess the common point ?

The bouncing ball is called a SPACE HOPPER. You can have fun sitting on it and hopping around without falling off !
The bridge is the LONDON MILLENIUM BRIDGE crossing the THAMES linking St Paul's Cathedral and Tate Modern and the Globe Theatre : it's only for pedestrians !

So, what could the common point be between a space hopper and the Millenium Bridge ? 

---

It's a record attempt which took place in April 2007 !

600 people had to hop together for a minute ! 
The previous record was in Oxford in 2003 and there were 551 space hoppers !
