They say that extraordinary claims require extraordinary evidence.
Without further ado, an actual record made from a tortilla playing "The Mexican Hat Dance" also known as "Jarabe Tapatío".
Why do this?
A while ago there was a satirical video featuring a tortilla jammed on top of a record player spindle.
In a way, it mocks the emerging trend and resurgence of vinyl and Record Store Day's tendency to release limited-run, colored records which are often resold for a much higher price by scalpers.
The video went viral and I wanted to see if I could actually make a tortilla record work without merely piping in some music in the background.
I was already familiar with cutting records on acrylic with a laser cutter for use in mechanical gramophones at 78 rpm, outlined in my instructable here.
It was in turn, modified from Amanda Ghassaei's instructable which was intended for 33 and 45 rpm on wood, paper, and acrylic.
In most grocery stores, there's a section of shelving dedicated to tortillas, usually categorized near the meat section.
Most of them will be cooked and either corn or flour.
Corn is a bit too lumpy for this purpose cooked or uncooked.
I found that the cooked tortillas tended to shred a bit when the outer cooked layer peels away from the inner less-cooked core.
Also, the cooked flour tortillas have uneven lumps as well from the cooking process.
I settled with uncooked flour tortillas made by Canasta which is found in most groceries. They are very soft, however, so try to get the ones that are as flat as possible near the bottom. The kind that are made without lard seem to keep the best at room temperature as well.
Unfortunately, Canasta seem to be the only brand of uncooked tortilla available in most groceries. They come in roughly 9" sizes.
The tracks on the outer edge of a record sound better because they are less compressed than those closer to the center. Therefore, the tortilla should be as large as possible. I could only get the tortilla to consistently make 7" records, the same as a 45.
I have heard that Costco sells Porkyland uncooked tortillas in 12" size. But I was only able to find them in the frozen section. The temperature difference may cause unwanted condensation when thawing out. In addition, they are not recommended to be stored at room temperature.
