Is the hoverboard ad real or a hoax? This week on The Feed

This week's most popular viral videos feature an adorable little girl conducting an choir, NASCAR champ Jeff Gordon pulling another Pepsi prank, a stunning dolphin stampede seen from above, jumping fitness gone wild and a questionable video that brings hoverboards to life.

First up, Jacko Unltd posted this interesting take on an already interesting fitness class.

In the next clip, stos2408 introduces us to adorable little Lara, who passionately performs the conductor role in her father's church choir.

Then, NASCAR superstar Jeff Gordon teams up with Pepsi again for another elaborate prank.

Captain Dave's Dolphin & Whale Safari shared this stunning drone footage on their YouTube page of a dolphin stampede, three gray whales migrating and a humpback whale calf snuggling and playing with its mom.

And, HUVrTech posted this convincing video that claims the hoverboards from classic 1989 film "Back to the Future Part II," are now a reality and will soon hit the marketplace.
