The fossil was discovered in the Dominican Republic and is thought to be 20-30 million years old, experts say. 

It is extremely rare to see fossils with air bubbles inside them, since there first must be water in the fossil, a phenomenon known as enhydro. The air bubble is then trapped in the water pocket. 

Amber is made of hardened tree resin and normally encases and immortalises forest-dwelling creatures.

The Twitter account 'Fossil Locator' posted the fascinating video of the air bubbles flowing through the fossil. 

'Enhydro (water inclusion) with a moving air bubble in amber from the Dominican Republic, 20-30 million years old, with plenty of insect fossils,' they wrote alongside the video. 

Amber is fossilized tree resin and its known for its striking orange colour.
