I like how Dr. Whooves doesn’t get irritated with Derpy interacting with his tinkerings.

Is it just me or is Derpy with her mane down a Rose Tyler reference?

she looks even more cute with her mane down

I guess you can say the shipping fuel for these two is quite…shocking.

derpamena?

Pffffhahahaha! XD

Or it’s just a gag.

It’s a “plasma ball”. Same thing as a neon tube, really. The ball in the middle is one end of the circuit, and the glass inner wall is the other end. The ball is partially evacuated, and the voltage difference sends an arc like a miniature lightning bolt through the gas. When you touch it, that changes the local voltage difference which moves the arc.
 
Plasma balls shouldn’t raise your hair like this, though. The animators are mixing them up with Van de Graaf generators, which produce a strong voltage difference on a sphere and anything the sphere touches (like a person).

I remember seeing something like this tesla ball irl but i didn’t get energized at touch.. Anyway, i just loved the Derpiwhooves part of the episode

Nice to see that one of my head-canons was confirmed here: Derpy enjoys getting electric shocks.

Hehe, SSJ Derpy <3

Aahhhhhhh omg plasma globes! I love those things! :D

I like how the Doctor is energized, too.

Derpy looks even cuter with loose hair.

She is a simple happy pony.
