    I liked today’s live video. You should have named one of the pigs porky, that would be good. I think you should put the thing in the gold shop, and I never knew about touch me not until today.

    A ardunio board being put in the gold store sounds amazing! I think you should call it the acellus board or the billings board. My science fair project includes a ardunio board, and a little bit of astronomy. Great episode today, I’m looking forward to Acellus World. I will be tuning in live! I wanted to share a quick idea for Acellus Academy. I think you should add something in Acellus, where we can comunticate with other students and/or teachers. Sort of like a discord server, but seprate it for different ages.
