Win 25 Gallons of Green Slime – It's as Easy as Following @HalloweenSci on Twitter


This contest has ended. Thank you for entering. Congratulations to our winner, Melitsa @playactivities!

You’ll be the hit of the party if you win 25 gallons of Spangler Slime – that’s 95 liters for those mad scientists who love the metric system. This isn’t some pre-made slime… no… it’s Spangler’s special PVA formulation for concocting the perfect batch of slime! If you’re the lucky winner, you’ll receive 25 gallons of green Slime Goo (the best PVA – polyvinyl alcohol) solution and Slime Cross-Linker (the linking agent that hooks it all together when you mix the two liquids). You mix it… you make it… and people go wild for slime.

About Spangler Slime – We believe along with thousands of other science teachers that the world’s best slime is made using PVA – that’s polyvinyl alcohol. But we’ll warn you that not all PVA is the same. Many people purchase cheap PVA solutions only to find growing bacteria floating around in the bottle after a few months. PVA can be the perfect place for bacteria to grow unless the solution has approved anti-bacterial additives. Spangler Slime Goo is made from a high-quality PVA with additives that kill bacteria and prolong the shelf life. It’s safe to say that SteveSpanglerScience.com sells more Slime solution than anyone in the country.

    I would take 5 gallons of the slime and put it in a “cauldron”, make treat bags in zip lock baggies and let the neighborhood kids dig in the slime for their treat bag on Halloween night. I would take 5 gallons and separate it into little containers for kids to take home with their candy. I would probably take the additional 15 gallons, walk down the street in the middle of the night to my best friends house and pour it over her car for a fantastic surprise!

    Some of my creative ideas for things to do with the slime are: wrapping the slime around firecrackers and smoke bombs, mixing the slime with diet soda and then adding the mentos, putting the uv beads in the clear slime and seeing if they still change colors inside the slime in the sun, and putting slime on someones keyboard as a prank.

    I like to add a little glow powder and play in the dark with my second graders. They mostly like to explore with it and we talk about the properties.

    My grade level work with Polymers for a science experiment and the kids love it.
    An idea for a Science Experiment using green slime.
    Students discover a weird goop made from corn starch that acts as a solid and a liquid. Then, they compare it to a rubbery material made from Elmer’s glue and Boraxo.

    I hope to win this…what a GREAT Halloween party my 4th grade class would have that Friday! I am excited to learn more – I am going to the Science Boot Camp in Orlando on Friday. I had to get a sub for the day, and need to leave the house no later than 5:30 AM, so I sure hope it is as exciting as the brochure claims it will be…..

    25 gallons of slime would go a long way as a reward for my students who want to “slime me” for acing their upcoming (required) 9 weeks exam….

    I love to use slime in our little kids science classes as well as ooey gooey. If I had that much I would put it in the water table at our Halloween trail event for the kids to feel. I might even put little plastic bugs and things in it to make it spooky but not scary. We could save some money on slime for a while too!! I buy it probably 4 times a year we love slime at the park district! I follow the experiment of the week!

    I checked @halloweensci for slime answers. The fifth graders in my ES want creepy for October and this offered slime would be just enough. I have been following Steve on twitter since he recommended it 2 years ago in Oklahoma City.
