How to tie dye milk–well, theoretically. It didn’t work quite as well as planned. You need to use high fat milk (2% or whole) to get the right effect. A drop of dish soap will cause the fat and water in the milk to mix, altering the surface tension and causing the dye to move. Learn how to do it (correctly) here.

I grew crystals in my fridge last night. They are also lavender scented. Here’s how I did it: About 2 cups of lavender scented Epsom salts. A glass jar. 1 cup of hot water (microwaved the water) ½ cup of additional hot water with food coloring of your choice (I used green) A fridge to put the jar of melted Epsom salts in over night.

Directions:

The ½ cup water, get it hot then you are gonna mix food coloring in it and set it aside.

Put your Epsom salts in the glass jar.

Take the full cup of hot water and pour into the jar over the Epsom salts. Stir for two minutes.

Take the colored water you had put aside and add it to the jar. Stir it up and then put the jar in the fridge (24 hrs)

When it is time to take the jar out of the fridge, it won’t look different at first do not get discurged! You have to get rid of the remaining liquid, once you do, the result will be your very own crystals grown by you!

Materials: 1.granulated sugar 2.food coloring 3.stovetop safe container 4. Cream of tartar 5.candy thermometer 6.light corn syrup 7.water 8.adult 9.aluminum foil pan 10.measuring utensils

Steps: 1. First, add one and three forts of sugar in the stove top safe container 2. next, add 1 cup of water 3.then, add half a cup of corn syrup 4.next, add 1/8 teaspoon of cream of tartar 5.then, combine all the ingredients 6. Next, slowly heat the heat the mixture at a low boil while stirring 7.then, keep the mixture add a low boil and please a candy thermometer in the container. 8.next, keep the mixture boiling until the temperature reaches 300 Fahrenheit 9.then, pour the mixture into the foil pan 10.next, add food coloring to the pan and spread the colors 11.finally, let the mixture cool until hardened.

Lesson: This experiment is used in candy making. When you add corn syrup, it prevents the sugar from re-crystallizing. The cream of tartar separates the sugar crystals into glucose and fructose, which are simple sugars. The light that passes through the translucent sugar glass will take the colors from the food coloring you choose
