Cool footage of a YouTuber inflating a four-foot balloon using dry ice before popping it in slow motion.

The video, filmed in Canada on Friday, shows the man using the scientific method to inflate the large balloon, which would have otherwise taken him 15 minutes of huff and puff.

When it has inflated by itself, he films himself popping it in slow motion.

He later wrote online: "I bought some huge four-foot dollar store balloons.

"It took too much effort to inflate them, so I turned to science."

"Dry ice pellets and water, and they inflate by themselves," he continued.

"Awesome slow-motion at the end for fun."

I bought some huge four-foot dollar store balloons. It took too much effort to inflate them, so I turned to science! Dry ice pellets and water, and they inflate by themselves! Awesome slow-motion at the end for fun.
