Today, we’re letting the science rip in a seriously gassy showdown. It’s helium versus neon! One is famous for making balloons float and voices squeaky -- the other is prized for its beautiful glow. Brains On star Sanden Totten and science writer and comedian Kasha Patel go head to head in this elemental debate. Which team do you think won?

Our judge for this debate is scientist and inventor Gitanjali Rao, who was recently named Time Magazine’s first-ever Kid of the Year!
