This is the amusing moment a Chinese physics teacher demonstrated a magic balloon ring in the classroom.

Mr. Tian Ruoping, the President of the Guilin Youth Science and Technology Education Association, captured the attention of all the pupils with a balloon experiment in Wenzhou, Zhejiang, China, on April 20.

Footage shows the presenter throwing a ring of colourful balloons in the front while a student holds the blower.

This left the young audience in awe from how amazing it was.

He then passed through the balloons without letting them fall to the ground.

The impressed students applauded him for the wonderful performance.

Mr. Tian said: 'The principle of non-falling balloons is quite simple, which is a key concept in fluid dynamics called Bernoulli's principle, named after the Swiss physicist Daniel Bernoulli, who published it in his book in 1738.'
