Week 5- Science

We all know that slime is fun, creative, and stress relieving; but it is also a great way to learn about science! This week, we’re focusing on the scientific aspects of slime and how to alter the make up of slime to transform textures and consistencies. The slime we’re making is jelly - it’s sizzly, stretchy, squishy, inflatable and poppy. It’s perfect for ASMR. Then we will have a science lesson on oobleck, experimenting with the transformative substance (technically a non-Newtonian fluid because it’s not a liquid or a solid; it doesn’t follow Newton’s Law). The class will end with instructions on how to make beautiful borax crystals over the weekend (there will be show and tell during the following week so we can see your creations). Lab coats, optional.

**Please note that we have changed the Zoom platform to be a Zoom webinar for the remaining weeks. You have received a new ID and PW to log on via email.**


  • Make sure your full name is displayed
  • Have all your supplies ready and near you (one of the bags are for “all weeks,” so please make sure you have that along with Week 1)
  • Try to get on the Zoom 5 minutes early
  • Please stay on mute during class
  • Raise your hand for questions (if it’s dire when we teach) but we prefer to have write us the chat box so we don’t lose too much time
  • Have your activator made and ready to go (a how to video is below in the next section)

Slime of The Week:

Learn how to make jelly slime, which is a beautiful texture that’s stretchy, inflatable and perfect for slime pops, pokes and sizzles. It is a fine art, much like making an intricate dessert. Our Kitchen and Experience Director, Sasha of @someotherslime, will be sharing the recipe we use and demonstrating it, step by step, so you can become a jelly expert.

Provided Materials:

  • 1 Bottle of Clear Glue
  • 1 Snowonder packet
  • Activator (mix 1 tsp of Borax powder with 1 cup of hot water until it fully dissolves)
  • 1 Bottle of Scent (your choice!)
  • Liquid Watercolor Pack
  • Charms of your choice
  • Slime Jar

Need to Gather:

  • Vegetable Glycerin (this week Lotion cannot be used as a substitute)
  • 2 Mixing Bowls
  • Spoon or Spatula
  • 1 tsp measuring spoon
  • 1 cup of water to inflate snow

Craft of the Week:

This week we will be making our favorite non-Newtonian fluid- oobleck! The coolest things about oobleck is that it is a pressure-dependent substance. This means that when it is sitting in your bowl it is a liquid, but when you quickly touch it the liquid turns in to a solid. Prepare to get a little messy with this one and keep paper towels on hand. We can't wait to learn more about it with you!

Provided Materials:

  • Liquid Watercolor Packet

Need to Gather:

  • 1-2 cups of Cornstarch
  • 1 cup of Water
  • Mixing Bowl
  • Spoon and spatula
  • 1/2 cup measuring cup

Oobleck Instructions:

  1. Pour 1 cup of water (any temperature) into your bowl
  2. Slowly add the cornstarch to the water 1/2 cup at a time; mix as you pour
  3. Once the mixture gets too thick to mix with your spoon/spatula start to mix with your hands. Break down any cornstarch clumps that form
  4. Continue to add cornstarch until you reach 2 cups total in your bowl. Oobleck requires a 2:1 ration of cornstarch to water
  5. Keep mixing the oobleck and add in a few drops of your liquid watercolor of choice
  6. Enjoy! The oobleck should become a solid when touched and then revert back to a liquid. If your mixture has a play doh texture when picked up then add more water

This week we have a crafty piece of (optional) homework for you. We want everyone to make and grow their own borax crystals! These beautiful creations are an amazing intersection of science and art. Grab a parent or grown up to help and have fun creating!

Provided Materials:

  • Borax Powder (3 tbsp per cup of water used)

Need to Gather:

  • 1 Pipe Cleaner (the color of the pipe cleaner will be the color of the crystals)
  • A pot to boil water in
  • ~1 cup of boiling hot Water (enough to fill 3/4ths of your jar)
  • Glass jar (no lid required)
  • 1 tbsp measuring spoon
  • A spoon or spatula
  • A pencil or pen
  • A piece of string (optional)

Borax Crystals Instructions:

  1. Our pipe cleaners will be the foundation of our crystals for the experiment. Take your pipe cleaners and mold them into whatever shape you want the crystals to turn out as.
  2. Take your pot and boil enough water to fill your glass jar 3/4ths of the way (~1 cup)
  3. Add ~3-4 Tbsp of Borax for every cup of water in your solution. Mix with your spoon or spatula until the borax has completely dissolved and the water has become clear again.
  4. Once your borax and water solution is mixed, pour into the glass jars until it is filled 3/4ths of the way
  5. Use the top of the pipe cleaners or a piece of string to tie your pipe cleaners to the pencil or pen
  6. Place the pencil or pen over the rim of your jar so that the pipe cleaners are suspended in the water.
  7. Let your submerged pipe cleaner sit for the next 24 hours. Your borax crystals will start to form and the longer you leave them the bigger they will get!
  8. Remove the pipe cleaners from the jar and you have your borax crystal! Let them dry and enjoy your amazing crystal creation. It will be a great accessory to the calm down jars we previously made!

Sounds of Sloomoo:

We’ll also be playing our theme song and discussing ASMR. Below is a link to both - the ASMR is the same track we have in our space, where you can listen with ear phones while you play with slime. You’re the only people we’ve ever sent this to!!!
