I've already shown you an easy last-minute prank involving toothpaste-filled Oreos, now here's a great joke involving an integral part of the cookie-eating experience—milk.
For this April Fool's Day prank, you'll be solidifying milk, which will befuddle your coworker, roommate, or significant other when they try and dip their Oreos, or even when they try and pour some milk for their bowl of cereal or cup of coffee. You could go the milk spilling all over the place route, but I think solid milk is just a little bit more aggravating.
This prank only needs about one day of advance planning, so make sure you start this one now.
The beauty of this trick is it also works with non-dairy milks like almond, soy, etc. Why should your vegan or lactose-intolerant friends be left out of the fun?
All you need to make solid milk is a container of milk containing at least two cups of liquid and a packet of unflavored powdered gelatin. Remember, you only need two cups. If you have more than that, pour out the amount you don't need for the joke and store it elsewhere so you can actually drink it afterward.
Mix the powdered gelatin with a couple of tablespoons of water and let it stand until it gets thick—this will take about five to seven minutes.
Heat the two cups of milk in the microwave or stovetop until warm, taking care that it doesn't get too hot or boil over. Add the gelatin mix to the milk and stir until the gelatin is dissolved.
Put the mixture back into the original container. It will take a few hours to set and become solid.
The good folks over at Martha Stewart suggest pouring the soon-to-be-solid milk into a glass pitcher or container because they're classy like that. Visually, it does look nice. However, we think it's more effective to pour it back into the original container since it's less likely to cause suspicion. After all, who decants their milk into a glass container? What are we, royalty?
If you really want to go the distance, you could swap out this milk/gelatin version with water/cornstarch, which will create a non-Newtonian fluid that'll make your friends even more confused when they try to dunk that Oreo in. The cookie will submerge fairly easy, but getting it out is killer. Check out this guide for instructions (just leave out the dye part).
