-
In one bowl mix 1/2 cup (4 oz.) glue and 1 ½ bottles (emptied glue bottle) of warm water. Add food coloring if you want colored slime.
-
In the other bowl, mix 1 teaspoon borax with 1 cup water until the borax is dissolved.
-
Add the borax solution to the Ziploc. Next, add the glue mixture to the Ziploc bag, close the bag and squeeze the mixture together.
-
The slime will begin to form immediately; stir as much as you can, then dig in and knead it with your hands until it gets less sticky. (No one makes slime without getting a little messy!) Don't worry about any leftover water in the bowl; just pour it out.
Observations:
(You can take this experiment as far as you like, depending on the age group and grade levels. Let’s test the properties of the Glueup!
-
Hardness: Roll the glueup into a ball. Press your sample with your index finger. Rate the sample from soft to hard, on a scale of 1-5.
-
Stickiness: Form a sample into a ball and place it in your hand. Rate the sample from less sticky to stickiest, on a scale from 1-5
-
Bounce: Shape the glueup into a ball. Hold the meter stick against the tabletop. Drop the ball from heights of 50 cm; 75 cm and 100 cm. Determine the height of the bounce.
-
Stretch: Form the glueup into a cylinder. Place the meter stick on the table. Starting from the 0 cm mark, pull the glueup cylinder until it breaks. Record the distance.
-
Shrinkage: Form the glueup into a cylinder. Stretch to a length of 10 cm. Measure the shrinkage at 10 sec, 20 sec and 30 sec intervals.
You have just tested Glueup A. Make up other solutions and test as follows:
a. Glueup B: 15 mL glue, 30 mL water, 10 mL borax solution.
b. Glueup C: 15 mL glue, no water, 10 mL borax solution.
c. Glueup D: 15 mL glue, 15 mL water and 20 mL borax solution.
d. Glueup E: Your secret recipe.
