Tinker Time Activity Recipes
Many parents have asked for recipes for some of the activities we have been doing in our preschool program. Here they are!

4 cups flour
2 cups salt (use 1 cup for a smoother dough)
2 table spoons cream of tartar
4 cups water
1/2 cup oil (not a nut oil)
Combine dry ingredients in a large pot. Gradually stir in water, oil, and food coloring (if using two colors add at the end after you split the batch, roll in color).
Cook over medium to high heat, stirring constantly until a ball forms and it is not gooey. Remove from heat, roll out onto counter and knead until smooth. Store in an airtight container, lasts for up to 8 weeks easily.
Finger Paint Recipe
1/2 cup cornstarch
3 Tbsp. sugar
1/2 tsp. salt
2 cups cold water
In a medium pan, mix all the ingredients together to make the finger paint.
Cook over low heat 10 to 15 minutes. Keep stirring the finger paint mixture
until it is smooth and thick. After the finger paint has thickened take the
pan off the stove and let the mixture cool.
After cooling, divide the finger paint into storage containers depending on
how many colors you would like. Add a few drops of food coloring to each
container. Stir the coloring in to the paint to determine the shade of
color. You’re ready to finger paint! Cover tightly when storing.
Basic Slime Recipe
borax (found in laundry detergent aisle0
food coloring (unless you want uncolored white slime)
There are two components to slime. There is a borax and water solution and a glue, water, and food coloring solution. Prepare them separately.
Mix 1 teaspoon borax in 1 cup of warm water. Stir until the borax is dissolved.
In a separate container, mix 1/2 cup (4 oz) white glue with 1/2 cup water. Add food coloring, if desired.
After you have dissolved the borax and diluted the glue, you are ready to combine the two solutions. Stir one slime solution into the other. Your slime will begin to polymerize immediately. The slime will become hard to stir after you mix the borax and glue solutions. Try to mix it up as much as you can, then remove it from the bowl and finish mixing it by hand. It's okay if there is some colored water remaining in the bowl. Store your slime in a sealed ziploc bag, preferably in the refrigerator. You'll want to chill the slime when you are not using it to prevent mold growth. The main danger to your slime is evaporation, so keep it sealed when you're not using it.
Frog Egg Moldable Slime
polystyrene beads (can be found in fabric stores)
This slime contains polystyrene beads, which makes it easy for kids to mold into shapes. You can sculpt with it or use it to coat other objects. You can store it to reuse it or allow it to dry, if you want permanent creations. As with slime, it's very safe, though anything containing food coloring can stain surfaces. Don't eat this slime, polystyrene beads simply aren't food.
Dissolve 2 tsp. borax completely in 1/2 cup (4 oz.) water. (2 tsp. of borax will produce a stiff product. If you want slimier, more flexible slime, then try 1 tsp. borax instead.)
In a separate container, mix 1/4 cup (2 oz.) white glue and 1/4 cup (2 oz.) water. Stir in food coloring.
Pour the glue solution and the polystyrene beads into a plastic bag. Add borax solution and knead it until it's well mixed. Don’t worry about extra water. Try adding some white glue to it and see if you are able to make more slime.
To keep your frog egg slime, store it in a sealed bag in the refrigerator (discourages mold). Otherwise, you can allow it to dry into whatever shape you have chosen.
How it works: borax reacts to crosslink the polyvinyl acetate molecules in the glue. This forms a flexible polymer.
Polymer Bouncing Ball
borax (can be found in the laundry detergent aisle)
Label one cup 'Borax Solution' and the other cup 'Ball Mixture'.
Pour 2 tablespoons warm water and 1/2 teaspoon borax powder into the cup labeled 'Borax Solution'. Stir the mixture to dissolve the borax.
Pour 1 tablespoon of glue into the cup labeled 'Ball Mixture'. Add 1/2 teaspoon of the borax solution you just made and 1 tablespoon of cornstarch. Do not stir. Allow the ingredients to interact on their own for 10-15 seconds and then stir them together to fully mix. 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.
Once the ball is less sticky, go ahead and bounce it!
You can store your plastic ball in a sealed Ziploc bag when you are finished playing with it.
Don't eat the materials used to make the ball or the ball itself.
1 can (14 ounce) sweetened condensed milk
1 T Cornstarch
10-15 drops food coloring
Pour the can of condensed milk into a saucepan.
Add the cornstarch and cook over a low heat, stirring constantly.
When the mixture thickens remove it from the heat and then add the food coloring.
Allow it to cool before playing or eating.
A little goes a long way!
This combination has been around for a long time, but it is always fun and easy to make.
Pour cornstarch into a large bowl.
Add food coloring to the water. Slowly add the water while stirring the cornstarch. Adjust the amounts of water and cornstarch until the Oobleck flows when you tip the bowl and feels solid when you hit it. Keep your Oobleck in the refrigerator to keep from getting moldy.
Feel free to add small objects to your Oobleck and try to dig them out.
