They’re best know for their soccer skills and FIFA gaming clips, but last week UK YouTube stars AJ3 (Andy Castell) and Charlie Morley filmed two videos with a difference as they took on two Guinness World Records title challenges.
The pair first took on the title for Most consecutive headers of a swiss ball in 30 seconds (team of two) - a record originally set by Dutch football legend Patrick Kluivert and British tennis star Heather Watson on the set of Sky TV show 'A League Of Their Own' back in 2014.
And y and Charlie then faced off against each other to see who could set a new record for Most headers of a swiss ball in 30 seconds.
They’re both incredibly tough challenges, but both Andy and Charlie were confident going in to the attempts.
Watch the clips to find out how the boys got on.
The pair took part in the attempt ahead of a live stream on Aj3’s YouTube channel which aims to raise funds for the charity TackleAfrica.
Tune in to Andy’s channel at 2pm GMT today to watch and get involved.
