Dunking Question

I just dunked a cake and it floated which means it's full of air. For the people that have done this before, in 24 hours will the cake NOT float anymore? I was thinking, if it still floats that means water never got into the cake and it's still full of air.

I'm not having trouble with my cakes, of course I put something heavy on mine so they are not floating. I'm just curious if water is ever really gonna get in the cakes, they seem airtight.
So I am asking the experience people if the cakes continue to float 24 hours later.

It doesn't necessarily mean it's full of air. It just means that the myc/verm mix Is less dense than water..... Same as a cork or something similar. Put a weight heavy enough to comPletely submerse it while dunking. This will allow for the cake to absorb the maximum amount of water possible.
To answer your question my cakes still float after dunking. If you are curious to know how much water it actually absorbed weigh it before and after. I haven't weighed them myself but I know they definately feel heavier.

have you ever taken a physics class before? not everything that floats has AIR in it.

That's a smart idea....weighing them before and after dunking.
Sorry to say but, if they still float 24 hours later they ain't gettin any water in them. It doesn't take much at all to make them sink or at least not float as much. I hope someone who knows for sure, absolutely with proof can answer this for me.

Well, I remember some of the algebra class I took 24 years ago so let's try something.
X = the density of the mycellium cake. Y = the density of water.
Z = X + Y (the cake absorbing water).
Even if the cakes absorbed a small bit of water, they might not sink but they certainly would not float all the way to the top of the water line as they do right before you start.
It's extremely hard to maintain an environment that is 95% humidity, extremely hard especially if you are drilling holes for fresh air into your fruiting chamber. That would make it next to impossible. I think I may have found a way to do this (taken from what I have learned here on the forum).
After reading many posts here, I discovered a great way to keep my inoculated jars around 80 degrees. I took a large plastic container and placed an aquarium heater on the bottom. Filled it up 3/4 with water and placed a smaller plastic box with my jars inside this larger box. Thermometer has been a solid 82 ever since and the heater is only set to half way.
I think taking a 10 gallon fish tank, installing an aquarium heater on the bottom and filling it up with water just enough to cover the heater. Then, slowly add perlite. In the beginning the perlite will be mushy but as you continue to add perlite it will dry up so you kinda have to feel it out. Put enough perlite so it's moist but definitely not mushy anymore should be perfect. Perlite is volcanic ash that absorbs 100 times it's weight in water then slowly releases the water into the air which makes it perfect for this. I believe that heated water beneath the perlite will accelerate the process and 95% humidity should be relatively easy to achieve. Definitely have to keep an eye on the water level. DAMN I wish I had some cakes to try this on. Seeing the success of my new inoculation chamber has me confident this theoretical fruiting chamber would work great. All ideas I got from this and other forums.
Thanks for the help and keep any and all ideas coming!!!!
