Try AsapSCIENCE on YouTube, White Rabbit Project on Netflix, Bill Nye Saves the World (also Netflix) or Mythbusters.

All are great science shows and they all have their own merits. Mythbusters has interesting visual effects, Bill Nye is pretty well known, White Rabbit Project has more pop culture, and AsapSCIENCE talks about the science of daily life.

I could go on for days, but I'll stop there :)
