Masterful demonstration - thanks for this guys!

Phenomenal. Thank you!!

By using the same bucket with old plaster bits, even tiny bits, it will start to set your plaster much faster. You can use that to your advantage but it's best to be aware of it as your mixing time will be shorter. There is no reason to have a dedicated mixer for the drill as long as it it cleaned afterwards. I like having a bucket of water nearby to dunk tools into.

A vibrating device is excellent for getting bubbles out of a viscous solution - just run it around the outside of the tub. Obviously a reasonably large massage device is better than trying to use one's phone.

Haha, don't endanger your phone. We do use a vibe table for ourselves. But we wanted to show how to make these for people with basic tools.

. Good video, but . . . . Just a tip. The tone and volume of you voice goes up and down, to the point where some of your words are inaudible. The music's volume doesn't help either. I would suggest that you turn the music down a little, while speaking up a little too.

What is the size of your slab? I'm thinking of making a plaster slab but I can't find how much I need to mix for the container I have.

Great video. I like the precise weights. I need to make me a good slab. Near the end you mentioned that there are 8000 grams of water that need to be evaporated out of the slab for it to be completely dry, but isn't a large portion of that water chemically bound with the plaster and will never evaporate?

You are correct, we misspoke.
