Niki & Gabi Test Their Knowledge During Slime Challenge!

Niki and Gabi DeMartino are putting a new spin on the slime challenge!

The 22-year-old YouTubers and twin sisters decided to up the stakes of the slimey video and test their knowledge of school curriculum!

“We wanted you guys to test us to see what we remembered from school,” Gabi explained.

The girls were asked questions across different subjects from science to history to math and if they got the answer wrong or didn’t answer the question first, they got slimed!

Check out the entire hilarious video below…
