In an incredible ultrasound video, Jen Cardinal's 14-week old baby was captured clapping his/her hands inside her womb.

As the baby clapped three times during a prenatal checkup, Jen's doctor rewound and scrubbed it while mum and dad sang "If you're happy and you know it, clap your hands."

While people are claiming that this isn't possible, and we haven't been able to confirm its authenticity, watch for yourself and and decide if it is indeed staged, or a miracle!
