This is the funny moment a boy banged his head on the glass door of a convenience store in Thailand.

Video shows the boy named Teem visiting the shop and accidentally hitting the glass doors in Prachin Buri province on January 31.

A frequent customer of the store, he strode confidently towards the entrance but walked straight into the transparent glass thinking there was nothing there.

Teem was instantly knocked back and was seen holding his head as he sat on the floor in disbelief following the glass door fail. The door was undamaged while the boy felt only slight dizziness after bumping into it.

He had visited buy some snacks but was unaware that the glass door had already been installed.

Shop owner Jum Thunchanok said: 'He comes to the shop to buy snacks for his brother every day. But when we expanded the shop and installed a glass door, Teem must have walked through the entrance too hard out of habit.'
