Materials: 15 ml of 60% Elmers Glue and water per student 15 ml concentrated borax solution. graduated cylinder plastic cups marked to 15 ml food coloring (different color for each class) zip lock bag What are the properties of the Elmers Glue? ________________________ What are the properties of the borax solution? _______________________ Procedure: 1. Pour 15 ml of Elmers Glue solution into a zip lock bag. 2. Add 15 ml of borax solution. 3. Press extra air out of the bag and seal the bag. 4. Kneed the bag until the mixture is completely combined and a rubbery ball forms. 5. Open the bag and form a nice ball. 6. Bounce only on hard surfaces, not a rug. What are the properties of the Glue Ball? _____________________________ __________________________________________________________________How does it differ from the original materials? ________________________ __________________________________________________________________ There are many extensions of this lab on the web. The chemistry of the cross bonding is also there.ZNDSET2H ڌM6*MDSET2H;<C ڈM6*MDSUM% Rilla ChaneyHDNISTYL &JSTYL x D t l d \ T L H7   -                    |HASH $ .;.  . .. . .... 0.
