Need some help with these two. No way for me to get any closer as they move in too large a pattern or two fast. Any ideas?

Don't think we can ID from that video. Buy some of the stuff suggested. If you want to buy methyl cellulose and make your own, here is how. I make a 2% solution
Materials
Beaker
stirring hotplate--This is actually very important
stir bar
distilled or spring water
methyl cellulose (I use 4000 cst, I think. Have to check the bottle)
scale
Methods
Place 100 mL of the water and the stir bar into a beaker
Bring the water to a boil while rapidly stirring, and I mean as rapid as you can
Turn off the heat
As soon as the water stops boiling begin slowly adding 2g of methyl cellulose
Keep stirring until the solution is room temp.
Why bring to a boil? Methyl cellulose is a bit odd. It's solubility increases as temps decrease. If you add it to room temp water then it will gel on the outside and form large clumps. These things are super annoying and super hard to get rid of. By adding it near 100 C and while rapidly stirring you keep it suspended and evenly distributed in the water. This way as it cools it will cool as a homogeneous mixture without clumps. Takes forever, but it is by far the best method I have read/used.
The above protocol should be applied to carboxymethylcellulose as well, if I recall correctly.
