We want to make YOU scream!
Ricky's been chatting to some researchers looking into the science of screaming, and even gave it a go himself - but can you do better?
Don't worry, we're not trying to scare you or upset you, but we just want you to record your loudest screams and send the audio to us. Check out some top screams below!
Georgina, 11, from North Shields got things started with this great effort.
Grace, 9, from Worcestershire decided one big screech just wasn't enough, so recorded three huge screams.
And 11-year-old Charlotte from Macclesfield in Cheshire must have been on the way to breaking the microphone with this ear-splitting attempt!
Want to send us a scream - this is how.
We want you to record your screams on a computer using a microphone or mobile phone and save them.
Which presenter screams the loudest?
Because there are so many different types of computer programmes and mobile phones around we can't explain exactly how to do it. You may need to get a technically minded parent or brother or sister to help you.
Once you've got a sound file we'd love you to email it to us at the address below. We know it says newsroundpix, but it is the right one!
E-MAIL your screams to: email@example.com
As well as the scream we want to know your name, age and the area you live in.
And please explain to anyone who can hear you before you start screaming what you're up to!
- DON'T put yourself or anyone else in danger.
- DON'T break any laws.
- DO get permission from your parent or guardian before sending us your scream.
- DO add firstname.lastname@example.org to your contacts.
