This is the stomach-churning moment two young girls are catapulted 100mph into the air on a slingshot ride with their terrified - and deafening - reactions caught on camera.

Footage shows best friends Carmarie and Kanya sat buckled into the device at the Indy Speedway park on Panama City Beach, Florida, over the weekend.

At the start they seem pretty calm but when the carriage tilts back and fires 300ft-high panic sets in and they let out manic screams with horrified facial expressions to match.

Both appear to pass out several times due to the extreme force, with their eyes glazing over and rolling back.

However, when they regain consciousness they continue screaming out their final wishes.

At one point Carmarie - who appears to be older - tells Kanya: 'If I die, tell my mama I love her.'

But her sidekick points out if she's going, 'honey... I’m [going to] be dead too!'

'Jesus mercy of killers,' she adds at another point.

Finally, after bungying up and down for around a minute the slingshot slows down, allowing the girls to catch their breath.
