Whenever you hear the word “resin casting,” your mind usually gravitates to objects you would normally dunk in a vat of resin. Things like wood, metal, or even mosquitoes cased in amber like in Jurassic Park. Rarely, if ever, you think of food.

YouTuber jedrek29t must have been thinking on an empty stomach a few months ago as he has decided to cast a McDonald’s cheeseburger and fries in resin to see if he could preserve this classic meal for future paleontologists to find:

All resin projects start with the creation of a mold, and these particular molds are made using 1 mm plexiglass. After pouring the first layers of resin and letting them dry (this is to keep the food suspended in the resin), jedrek29t carefully places the burger and the fries into their respective containers.

Here comes the part you’ve all been waiting for. To be honest, the resin looks more like a clear syrup when poured onto perfectly palatable food, but you still shouldn’t eat it. Since McDonald’s burgers usually look like they’re made of plastic, the resin covers this cheeseburger quite nicely.

The fries are a different story. Since potatoes absorb liquids, the resin turns these already soggy fries into shriveled, brown shadows of their former crispy selves. He uses a couple of fries to fit the plexiglass mold before filling the entire container with clear resin.

Now you would think this is where the project ends, but jedrek29t does us kindness and shows us just how permanent these molds are. He leaves his molds out for 60 days and documents the change in the appearance of the foods inside.

Since the resin prevents air from making contact with the food, the burger and fries remain mostly untouched by mold or insects. The top of the burger bun does shrink a little due to lack of air.

Curious to see if the food still smells good, he cuts open the molds and inspects his burger and fries. While the fries have long since lost their odor, jedrek29t swears he can smell the cheeseburger emanating once he cuts the mold.

Eager to see what will happen if he leaves these out for another 60 days, he then covers one side of the opened burger and fries in resin and hardens them with a UV light. The other halves of the foods, on the other hand, are left uncovered and open to the elements.

As you would expect, the resin-covered exhibits (the ones on top) have remained unchanged and the open ones have started to fill up with… well, mold.

What’s interesting to see is that the fries haven’t actually changed that much, whether or not they are covered with resin. This is most likely due to the potatoes absorbing the resin during the initial pour. The same can’t be said about the burger though, as you see the presence of the white mold mound on top of the burger bun.

This is by no means a good way to preserve your McDonald’s meals. While it looks visually interesting, the fact that you just dunked your food into toxic resin makes it completely inedible. So, I suggest just get yourself a good refrigerator.

Jedrek29t casts tons of things in resin on his YouTube channel, most of which look way more visually appealing than an expired McDonald’s combo meal.
