We have reached the modern age.
This video has it all:
A) A really, really cool product
B) A young child learning about the world (ohhhh, how beautiful)
C) A father, equally as amazed as the child
D) The young child telling the father off: it's the best part of the whole video. The father gives the classic, "We used to have to fill these individually when I was a kid!"
The child replies,
Dad gets schooled by kid. Well done to the youngster.
