Ok. Not that kind of acid. Hydrochloric acid to be exact....I used it to test for zinc in bird toys and metal for potential use for bird toys....Urgh. Sleepiness. Watch the vids and you'll see. I also have more detailed blurbs in the comments. Included in this batch is a rough vid on making tube toys with non-toxic glue, and a short discussion on macaw food.
Later, I'm hoping to do a separate vid on making the glue.
And...I still have yet to actually do something to the sketchbook. =_= I have ideas, just haven't gotten to them yet.
