LEAP Telephone Workshop a Great Success

Yesterday's LEAP Telephone Workshop was a Great Success and this is why:

1) 50 kids learned how voice becomes electric current and back to voice, then one of them asked, "why is current labeled "I" and not "C"?"

2) 50 kids learned how to dial a rotary phone, then one of them asked, "are rotary mechanisms more complicated than a cellphone?"

So, was the workshop a success or not?

Consider buying a perk, and tell me what you think!
