2. Gak (Slime) EXPERIMENT 1.Empty the entire bottle of glue into a mixing bowl. 2.Fill the emptied glue bottle with warm water, replace the lid, and shake. 3.Pour the glue-water mixture into the mixing bowl and use the spoon to mix well. Add a drop or two of food coloring, if desired. 4.Measure 1/2 cup of warm water into the plastic cup and add 1 teaspoon of Borax powder to the water. Stir, and then you have your Borax solution. 5.While stirring the glue in the mixing bowl, slowly add a little of your Borax solution. Immediately you’ll feel the long strands of molecules starting to connect. 6.Abandon the spoon and use your hands to do the serious mixing. Keep adding your Borax solution to the glue-water solution (don’t stop mixing) until you get a perfect batch of slime. You might like your slime more stringy while others like firm slime. 7.When you’re finished playing with your slime, seal it up in a zipper-lock bag for safe keeping.

MATERIALS:  white glue (8 oz. bottle)  1 teaspoon Borax powder (a powdered laundry soap found in the grocery store)  mixing bowl  plastic cup  spoon  measuring cup  measuring spoon  ½ cup warm water  paper towels  zipper-lock bag  food coloring (optional)

3. Oobleck EXPERIMENT: 1. Mix ingredients together in a tray 2.The proportions of the cornstarch and water may need some adjustments, depending on your ideal consistency. 3.Explore the properties of the mixture (in other words, play!) EXPERIMENT: 1. Mix ingredients together in a tray 2.The proportions of the cornstarch and water may need some adjustments, depending on your ideal consistency. 3.Explore the properties of the mixture (in other words, play!) MATERIALS:  ¾ cup corn starch  1/3 cup water  measuring cup  food coloring (optional)

4. Bouncy Balls MATERIALS:  2 plastic cups  zipper-lock bag  stirrer  2 tablespoons warm water  ½ teaspoon Borax powder  1 tablespoon white glue  1 tablespoon cornstarch EXPERIMENT: 1.Label one cup 'Borax Solution' and the other cup 'Ball Mixture'. 2.Pour 2 tablespoons warm water and 1/2 teaspoon borax powder into the cup labeled 'Borax Solution'. Stir the mixture to dissolve the borax. Add food coloring, if desired. 3.Pour 1 tablespoon of glue into the cup labeled 'Ball Mixture'. 4.Add 1/2 teaspoon of the Borax solution (NOT Borax powder!) you just made and 1 tablespoon of cornstarch. Do not stir yet! 5.Allow the ingredients to interact on their own for 10-15 seconds, then stir them together to fully mix. 6.Once the mixture becomes impossible to stir, take it out of the cup and start molding the ball with your hands. The ball will start out sticky and messy, but will solidify as you knead it. 7.Once the ball is less sticky, go ahead and bounce it! 8.You can store your plastic ball in a sealed zipper-lock bag when you are finished playing with it.

5. Play-doh MATERIALS:  large pot  mixing spoon  2 cups warm water  2 tablespoons vegetable oil  2 cups flour  1 tablespoon cream of tartar  1 cup salt  optional: o food coloring (liquid, powder, or unsweetened drink mix) o scented oils EXPERIMENT: 1.Mix all of the ingredients together in a large pot 2.Stir over low heat. The dough will begin to thicken until it resembles mashed potatoes. 3.When the dough pulls away from the sides and clumps in the center, remove the pan from heat and allow the dough to cool enough to handle. 4.Keep stirring and cooking until the dough is dry and feels like Play-Doh **IMPORTANT NOTE: if your dough is still sticky, you simply need to cook it longer!

6. Air-Dry Cinnamon Clay MATERIALS:  rolling pin  bowl  cookie cutters  1 ½ cups ground cinnamon  1 cup applesauce  ¼ cup white glue  plastic wrap  wax paper  ribbon or yarn  drinking straw EXPERIMENT: 1.Mix cinnamon, applesauce, and glue together in a bowl. The dough should be as thick as cookie dough. Add a bit of water if the dough is too stiff. 2.Remove from bowl and knead with hand. Put it back in the bowl, cover with plastic wrap, and let sit for at least 30 minutes. 3.Remove the dough, knead again to make sure it's smooth. 4.Flatten/roll the dough between waxed paper until it's between 1/4" thick and 1/8" thick. 5.Cut out desired shapes and use a straw to punch a hole for the ribbon to hang. 6.Gently place the shapes on a piece of clean wax paper. They will take 3-5 days to dry. You may need to turn them over a couple of times a day for them to dry evenly and flat. 7.When dry, thread a piece of ribbon or yarn through the hole to hang.

7. Microwave Salt Dough MATERIALS:  ½ cup salt  ½ cup water  1 cup of flour EXPERIMENT: 1.Add ½ cup of salt and 1 cup of flour to a bowl. 2.Slowly stir in the water- you may not need the entire ½ cup. 3.You want the dough to be dry – if it gets too sticky, add more flour. 4.Knead the dough and then roll out and use as you want. 5.Once you have made the shapes you want, then you need to dry them so you can paint. Traditionally salt dough is dried in the oven which takes around 3 hours at a low heat so they don’t burn. Instead, cook in the microwave for 3 minutes. 6.If they are still a little wet when the time is up, just put back in for another 20 seconds at a time until done. 7.Leave to cool down and then paint, if desired.
