Woman shows video as a warning to always wash balloons before blowing them up

People are flooding to social media in horror after a TikToker revealed why you should 'wash your balloons' prior to blowing them up.

Prepare to turn away if you'd rather not know what you're inhaling when you blow up balloons:

It may've been fun to blow up balloons as a kid, but somehow it becomes even more of a ball-oon ache to huff and puff the older you get, particularly not helped if you had a heavy one the night before, the plasticky taste doing nothing to help your hangover.

The video shows an assortment of pink, white and shiny purple balloons submerged in a tub of foamy water.

Danielle moves the balloons to the side with her hand to reveal the colour of the water underneath. And let's just say it looks like the shade of water your bath turns after you've been out at work, travelled on the tube all day, then played some sport and also been on a night out.

And the caption adds: "There's no way."

Other TikTok users are flocking to the post in horror over Danielle's revelation as to just how dirty the insides of balloons are.

"No NO but," a second wrote.

A third commented: "Right, never blowing up balloons again xx."

However, others weren't too phased, and some simply suggested other ways to blow up balloons instead.

A person said: "Who blows up balloons with their mouth?"

"Who has time for that still alive after all these years," another argued.

A third echoed: "Oh well builds the immune system."

And a fourth resolved: "Or just use a pump."
