Watch a compilation of all the clips in the video above. 

1. Hoverboard record

Canadian develops futuristic hovercraft7:51

Our top viral video of the year soared high above the rest with 1.9 million shares on the CBC News Facebook page

In May, Montreal inventor Catalin Alexandru Duru broke the world record for the longest hoverboard flight.

Duru flew up to five metres above a lake for a distance of 275.9 metres aboard his homemade, propeller-powered hoverboard on a trip that lasted more than 1.5 minutes.

Now, the 31-year-old Duru and his company, Omni Hoverboards, are working on a secret, next-generation version of the device.

2. Interactive beer pong

RAW: Inventor shows off interactive beer pong table0:45

When Saskatoon's Jeff Nybo started a Kickstarter campaign for his homemade beer pong table he never imagined it would get so much attention

His custom-made tables, which he calls the BPT X5, feature flashing LED lights, a ball washer and a touch-sensitive tabletop that keeps score.

It wasn't long before his Kickstarter page had surpassed his fundraising goal by $40,000 and been viewed by millions online.
3. Breathing forest floor

Trees 'breathe' under forest floor1:36

Who could forget this magical video?

Captured by a hiker in Apple River, N.S., the video shows a heaving forest floor that appears to be breathing.

The explanation — though less magical — was no less fascinating. The tree roots, spread out wide underneath the forest floor, had detached from their moorings, creating the effect of "breathing" when the trees caught the wind.

As cool as the effect was, it will probably be short-lived.

The wind will likely blow the trees down soon.

4. Mermaid tails

What do you give a kid who has everything?

A sparkly mermaid tail, just like Ariel's from Disney's A Little Mermaid, apparently. Of course, you don't need to be a kid to enjoy them, say adult mermaids.

In 2015, sparkly mermaid tails were all the rage and special mermaid schools started popping up to teach swimmers how to use them.

There were some safety concerns, but that didn't stop the tails from making a big splash this year.

5. Cat yoga

Yoga with cats raises money for orphaned kitties1:44

There was hot yoga, laughter yoga, even paddleboard yoga, but 2015 brought us cat yoga too.

In September, Stretch Vancouver studios hosted its first Cats on Mats, a human/kitty yoga class wherein eight kitties pawed and purred their way into our hearts. 

Cats on Mats was held to raise funds for the Vancouver Orphan Kitten Rescue Association, and was jointly organized by Catfé — Vancouver's first cat cafe.  

There's another cat yoga class scheduled for the New Year.
