How to Make Valentine Slime
Making homemade slime is a process that can easily go wrong, but if you follow the directions in this post exactly, you can make Valentine slime that will turn out perfectly and delight friends and family of all ages.
How do you make Valentine’s Day slime?
Making Valentine slime is easy! For Valentine slime, all you have to do is mix equal parts Elmer’s glitter glue and Elmer’s slime activator.
Adding some baking soda can add additional texture to the slime, and adding little plastic hearts make the slime into a true love potion slime!
Slime Science for Kids
Wondering how slime is formed? Here is the science behind our Valentine slime recipe that we’re making today.
The main ingredient in slime is something called a polymer.
Polymers are long chains of molecules that are flexible and can stretch.
In slime, we use a type of polymer called polyvinyl alcohol or PVA. When you mix PVA with water, it forms the base of your slime.
Imagine you have a bunch of strands of spaghetti in a bowl. If you add something sticky like glue to the spaghetti, it would stick them together.
In slime, we use something similar called a cross-linking agent. Borax or liquid starch are common cross-linking agents. They help the polymer strands stick together, creating the slimy texture we love.
Viscosity is a fancy word that describes how thick or thin a liquid is. Slime has a unique viscosity—it’s thick and gooey, but it can also stretch and flow.
This is because of the way the polymer chains and cross-linking agents interact.
When you play with slime, you can feel its viscosity as you stretch it and watch it ooze between your fingers.Slime behaves like what scientists call a non-Newtonian fluid.
This means its viscosity changes depending on the force applied to it. If you slowly pull slime, it stretches easily like a thick liquid.
But if you pull it quickly or hit it, it can act more like a solid, resisting the force. This is why slime can bounce and even break apart when you pull it quickly.
So, when you make and play with slime, you’re exploring the science of polymers, cross-linking, viscosity, and non-Newtonian fluids—all while having a lot of fun!

Fun Facts about Love Potion Valentine Slime
Did you know that the color of your slime can impact your mood? Or that astronauts once conducted experiments with slime in space?
Borax, a common slime activator, was first discovered in the dry lake beds of Tibet. It has been used for various purposes throughout history, including as a cleaning agent and a component in pottery.
The main ingredient in slime, often a polymer like polyvinyl acetate (found in glue), forms long chains that give slime its unique stretchy and gooey properties.
The color of your slime can impact your mood! For example, blue is often associated with calmness and tranquility, while red can evoke feelings of passion and excitement.
The term “slime” was first mentioned in the context of children’s play in a 1976 book titled “How to Make Slime” by Susan Spigarelli.
You can make slime magnetic by incorporating iron oxide powder into the mixture. This allows you to manipulate the slime using a magnet.
Some slimes can be made entirely edible! Ingredients like marshmallows, cornstarch, and flavored extracts can be used to create a safe and tasty slime.
Adding thermochromic pigments to slime allows it to change color with temperature variations. Imagine the delight of seeing your slime transform at the touch of your hand!
In 2019, astronauts aboard the International Space Station conducted an experiment to see how slime behaves in microgravity. The results provided insights into fluid dynamics in space.
Slime has gained so much popularity that there are now slime festivals and conventions where enthusiasts gather to share their creations, attend workshops, and even participate in slime competitions.
The largest batch of slime ever made weighed a whopping 6,318 kilograms (13,934 pounds) and was created in the United Kingdom in 2018.

STEM Extension Ideas to Use While Making Slime
Beyond the enchanting gooiness, we’ll explore scientific phenomena, harness technology, delve into engineering marvels, embrace design thinking, and unravel mathematical mysteries.
Have students record observations, measurements, and predictions throughout the slime-making process. Encourage them to use scientific notation and draw diagrams.
Explore the engineering aspect by designing and 3D printing custom molds for slime shapes. Students can learn about the design process and experiment with different mold designs.
Turn slime-making into a mathematical modeling activity. Ask students to predict the ideal ratios of ingredients for the perfect slime and create graphs or charts to represent their findings.
Experiment with the impact of temperature on slime consistency. Have students create slimes at different temperatures and analyze how it affects the texture, stretchiness, and overall properties of the slime.
Focus on precision in measurement. Challenge students to create the most accurate slime by precisely measuring ingredients using different units. Discuss the importance of accuracy in STEM disciplines.
Explore the science of sensory perception. Have students conduct experiments to test how different textures, colors, or scents in the slime impact people’s sensory experiences.
Challenge students to explore alternative slime activators. Discuss the science behind various activators like contact lens solution, saline solution, or laundry detergent. Encourage them to design their own safe and effective activator.

Instructions
- It’s time to get sticky! Start off by grabbing your glue and empty it into a large bowl.
- Afterward, pour approximately ¼ cup of warm water into the empty glue bottle until it's about one-third full, then securely seal the lid. Shake the bottle thoroughly to mix the remaining glue with the water. Transfer the mixture into the bowl containing glue and stir until well combined.
- Next, add the baking soda to the glue and stir to mix thoroughly.
- Now you can get creative! Feel free to put additional glitter, food coloring, scents, or confetti. Make sure to stir it into the glue mixture before adding the slime activator.
- Let’s put our love potion to life! Add slime activator to the glue mixture and stir well. Add the slime activator slowly, mixing between additions, and add only enough to bring the glue together into a soft ball.
- Things are just about to get even more fun! Remove the slime from the bowl. The slime will be sticky. Begin to play with the slime, stretching or kneading it as you would bread dough, to bring the slime together. The slime is ready when it is no longer sticky.
- Voila! Your very own Love Potion Valentines Day Slime is complete!.
