Oobleck, Slime and Flubber Oh My!

October 21, 2007


Last week I volunteered to help the Brownie Troop Leaders with decorating the Troop 3324 table at the Monster Mash that was held last night… Normally this would be done with the entire troop, but, with a Cheerleading competition and a birthday party among other obligations this week, the leaders left it to me and Big Girl to come up with a theme and do the decorating…

Big Girl and I discussed a bunch of ideas and picked to do a ‘Witch’s Kitchen’… I brainstormed some ideas, did some googling and came up with the following science projects (ok, yep, the Science Geeks strikes again)… and collected the household items I needed (and purchased those I was missing) and off we went… We made this a ‘family’ activity, at least with the littles while big guy worked in the basement and on other projects…

We made the following (the links are to Science Cafe):

Oobleck, a dilatant… a substance that at times appears liquid, or solid.. depending on the amount of pressure applied… think… the way the sand behaves right at the line where the wave pulls back into the ocean… how your feet can sink down into the sand… or… if you stand on certain areas.. it appears to get harder and the water appears to drain away and the sand starts to look dry… oobleck is made from water and corn starch.. it can be rather messy though… so a good outdoor activity, or non-carpeted area… I didn’t take pictures of this… I was too busy cleaning up messes 😉

Slime… ooh fun stuff… Slime is a polymer (many parts)… and is a lot of fun to play with… it’s cleaner than oobleck, but still, it breaks into little pieces easy, and think about picking up tiny pieces of ‘jello’… it’s not terribly easy is it… so well protected area for playing… we went with the tiled kitchen floor… polymers in our body make things stretchy, but stable… (think about blood vessels that relax and stretch as the blood pumps through our body.. but yet, maintains its original shape… the actin and tubulin (natural polymers in our bodies) help the muscles of the blood vessels to behave this way.. )

We colored ours green… for the ‘Ghastly Ghost Goop’ that we called it…




Flubber, (also a polymer, like Slime) is made from the same ingredients as Slime, but with a slight twist (white glue instead of gel glue, and slightly different amounts of the ingredients)…


Step 2ish? The soap solution and glue solution are poured together


Mixing… the polymer molecules are forming… (looks like a slimy mess)


What kid doesn’t like to get their hands all disgusting and slimy… aka ‘Kneading the flubber’


The finished and definitely most popular product!

Next up… The decorating…

Now with a witch’s kitchen.. if you’re like me… and Big girl … you imagine, bubbling cauldron, old creepy bottles of scary ingredients… a scary black cat.. that sort of stuff..


Here are the bottles we came up with…


Dragon’s Blood (corn syrup, water and food coloring)


Gummy Tongues and fingers from the Halloween Candy aisle…


Flubber (named and later labeled… ‘Gary The Snail Slime’), Bat Droppings (aka Jimmies), and Giant Biting Fly Larvae (aka gummy worms)

Missing from the pictures…

Octopus eyes (gummy eye candies in vegetable oil), Freeze Dried Flesh Eating Fly Larvae (aka minute rice), and ‘Ghastly Ghost Goop’ (slime)..

For the ‘authentically OLD’ look to the bottles I created labels using Microsoft Word, a Harry Potter Font, and strong coffee… (I printed the labels on plain paper, crumpled them up and then re-flattened them, then soaked them for a minute or 3 in STRONG coffee.. I let the papers dry on Freezer Paper and then just laying on the stove top)…

I searched a while and found a distributor of dry ice to create our bubbling cauldron and managed to get a 2 pound brick (think extremely cold snow… not hard as a brick)…

Finally, we created a lava lamp with instructions from here and placed it on top of a pumpkin light for colorful effects…


Here’s our finished table.. (we left out bowls of flubber and slime for the brownies to play with… it seemed to be a popular table, even though we didn’t win any prizes…)



oh… and the finished kitty… (her hat was not worn for her parties as she would be too hot.. so we made a headband for the parties, and she’ll wear the hat for trick-or-treating…)


Now… let the relaxing begin 😉

    That’s such a sweet thing to do. I think you deserved plenty of prizes for that, I especially liked the flubber.
