	~~Elementary School, Middle School, High School~~		This is a classic hands-on demonstration that students will love to play with. Be sure to bring plenty of supplies, and towels will be handy for spills!

	~~== Format ==~~

	~~Hands~~-on

	== Materials ==		== Materials ==

	Water		* Borax Powdered Detergent
	~~Borax (sodium tetraborate)- available in the laundry section of most grocery stores~~		* Water
	~~Elmer’s glue (not the washable kind)- also available at any general store~~		* 1000mL Bottle
	Popsicle ~~sticks or spoons~~		* Elmer's Glue or Similar
	~~Large mixing bowl~~		* Dixie Cups
	~~Ziploc bags~~		* Popsicle Sticks
	~~Paper towels~~		* Plastic Sandwich Bags
			* Optional: Food Dye

	== Safety Precautions ==		== Safety Precautions ==

	~~Science Theatre demonstrators must keep the safety of themselves and their audience in mind at all times. All Science Theatre demonstrators must have~~ read ~~through~~ the Safety Training page. The ST Safety Box with first aid kit, fire extinguisher, etc. should always be available to demonstrators. Always wear safety gloves, glasses, and a labcoat if handling chemicals; always perform potentially dangerous demonstrations at a safe distance from the ~~audience; and always keep a very close eye on any volunteers you call from the audience. Creates a non-toxic slime, but eating it is not recommended.~~		Please read the General Safety Precautions section of the [[Demonstration Safety]] page before performing this demonstration.

	~~== Preparation ==~~

	~~Create a super saturated solution of water and borax~~.

	== Demonstration ==		== Demonstration ==

	~~Add Elmer’s glue to the solution (2 tablespoons~~, ~~but measuring not necessary) Stir rapidly with Popsicle stick. Check~~ the ~~slime, if~~ it ~~is very sticky keep stirring it in~~ the ~~borax solution~~, ~~if it is no longer sticky proceed to step 5~~. ~~The slime should feel very runny~~ and ~~be difficult to hold in your hands~~. ~~Scoop out~~ the ~~slime~~ and ~~knead between hands. The longer~~ you ~~knead the more putty like the slime will become. Store slime in a plastic bag, if it starts to dry out~~ add ~~more water~~.		# Set out cups and popsicle sticks. If not already mixed, pour 900mL of water into the bottle and add Borax until it reaches the 1000mL mark or the Borax stops dissolving, whichever comes first.
			# When students come up, give each one a cup and a stick. fill their cups one third of the way with glue, and if you have food dye let them add 1-2 drops. Have them start mixing the glue, and as they do pour a small amount of the borax solution into the cup, filling it to the halfway mark. As they continue to stir, the glue will clump up and become a glob of slime!
	~~== What to Say ==~~		# Once they have made their slime, they can scoop it out of the cup and play with it. Give them a bag to store it, and they can take their slime home with them!

	Have ~~the kids add~~ the glue and ~~stir~~ the ~~glue~~ into the ~~borax solution~~. ~~Explain that this is~~ to ~~change~~ the glue ~~into slime by causing it to form long molecular chains. The slime~~ will ~~feel very wet~~ and ~~gooey at first; this is~~ a ~~result~~ of ~~too much borax. Have the kids knead the~~ slime, they ~~usually enjoy getting their hands all slimy~~. ~~The kneading will cause excess borax~~ to ~~evaporate or be absorbed leaving a Silly Putty-like substance behind.~~

	== Why ~~It Is~~ ==		== Why This Works ==

	~~Mixing glue~~ with water ~~creates a polymer (polyvinyl acetate);~~ the borax ~~links~~ the ~~polymer chains together~~.		The Outrageous Ooze is a classic demonstration that introduces kids to chemical reactions. There are several ways to tell if something has undergone a chemical reaction, with some examples being:
			*A change in the ''color'', like a shiny iron nail rusting and turning brown!
			*A change in the ''state of matter'', like a liquid cake batter baking and becoming a solid cake!
			*A change in the ''temperature'', like a piece of wood lighting on fire and becoming hot!
			*A change in the ''appearance'', like a glow stick starting to glow after being activated!
			*A change in the ''compounds'', like mixing vinegar and baking soda and getting a foam explosion made of water and carbon dioxide!
			When we mix the borax solution into the glue, the borax reacts with the glue, causing it to clump and stick to itself. When the glue starts to stick to itself, it traps some of the water inside, which makes it behave like slime. This change from a liquid, sticky glue to a more solid, non-sticky glue means that we had a chemical reaction happen!

	== ~~Real Life Examples~~ ==		== Additional Information ==

	~~Polymers are used all~~ the ~~time around the household~~. ~~Plastic, nylon, and clothing all contain polymers. For example~~, ~~fishing line or any plastic object is made of polymers. Gak (if anybody remembers that from when it was cool…) is a very similar polymer (polyvinyl alcohol) to what this experiment creates.~~		* This demonstration works well with the [[Oobleck]].
			* You can bring other add-ins for this demonstration, such as sparkles!

== Safety Precautions ==

Science Theatre demonstrators must keep the safety of themselves and their audience in mind at all times. All Science Theatre demonstrators must have read through the Safety Training page. The ST Safety Box with first aid kit, fire extinguisher, etc. should always be available to demonstrators. Always wear safety gloves, glasses, and a labcoat if handling chemicals; always perform potentially dangerous demonstrations at a safe distance from the audience; and always keep a very close eye on any volunteers you call from the audience.

== Preparation ==

Create a super saturated solution of water and borax.

== Demonstration ==

Add Elmer’s glue to the solution (2 tablespoons, but measuring not necessary) Stir rapidly with Popsicle stick. Check the slime, if it is very sticky keep stirring it in the borax solution, if it is no longer sticky proceed to step 5. The slime should feel very runny and be difficult to hold in your hands. Scoop out the slime and knead between hands. The longer you knead the more putty like the slime will become. Store slime in a plastic bag, if it starts to dry out add more water.

== What to Say ==

Have the kids add the glue and stir the glue into the borax solution. Explain that this is to change the glue into slime by causing it to form long molecular chains. The slime will feel very wet and gooey at first; this is a result of too much borax. Have the kids knead the slime, they usually enjoy getting their hands all slimy. The kneading will cause excess borax to evaporate or be absorbed leaving a Silly Putty-like substance behind.

== Why It Is ==

Mixing glue with water creates a polymer (polyvinyl acetate); the borax links the polymer chains together.

== Real Life Examples ==

Polymers are used all the time around the household. Plastic, nylon, and clothing all contain polymers. For example, fishing line or any plastic object is made of polymers. Gak (if anybody remembers that from when it was cool…) is a very similar polymer (polyvinyl alcohol) to what this experiment creates.
