DIY best Slime recipe

Empty the bottle of glue into a mixing bowl. Add water and mix, then add the liquid starch in increments stirring with each addition. When the slime comes to a doughier consistency Add more starch if needed if slime is sticky. Store in a plastic bag or container. Slime can get moldy so store in the fridge to extend its lifetime.  

Color Changing Slime Experiment

This really was the fun part… Coming up with ways to make the slime change color. Putting it on soda cans, frozen water bottles and heat packs. Holding it with hands that have held something hot or cold. Breathing on it. Using it as a thermometer (the pigments we used go clear at 71.6 ºF so we could tell whether it was hotter or colder than that.) This is really fun experiment. Try different pigment colors with different food coloring.

St Patrick Day Green Carnations experiment

I kept my carnation out of water for 2 hours before I placed it in the color water.   This is a great hands-on experiment with your kiddos. Don’t pass up those white carnations in the stores. Your going to be able to witness Capillary Action of water in plants.   Most of the time, plants get their water from the ground. This means that the plant has to transport the water from its roots up throughout the rest of the plant. How is this done?   Well good question, Water moves through the plant by means of Capillary action….

Fireworks in a jar Experiment

Fireworks in a jar – Oil and water don’t mix because of how their molecules are constructed. Water is what is known as a polar molecule and Vegetable oil, on the other hand, is a nonpolar molecule.   You also noticed that food coloring only mixes with water . . . and now you know why. Food coloring is a polar molecule because it dissolves in water. In other words, food coloring and water are miscible. Vegetable oil is not affected by the food coloring because they are polar opposites.   The oil is less dense than the water, it…

WORLD’s FASTEST Naked Egg (Rubber Egg, Bouncy Egg) Experiment

I’m going to show you how to make a naked egg lighting FAST. When you use Calcium, Lime, Rust Remover (CLR) your naked egg will be ready in under 2 hours. Make sure you read the cautions on the container. I used gloves, in a ventilated area and googles. Adult supervision is required.   CLR is guaranteed to be the easiest and fastest method of quickly dissolving calcium. Hence the name Calcium Lime Rust remover.   The reason the egg shell dissolves in White Vinegar, Red Wine Calcium, Lime, and Rust Stain Remover is the Acid breaks apart the calcium…

Can You Walk on Water? (Non-Newtonian Fluid Pool)

15 boxes of Cornstarch and were walking on Oobleck! Mix one box at a time in a separate bowl and then poured into the tub.   What is happening? You’ve essentially made homemade quicksand or a large tub of oobleck. Corn starch in water displays interesting properties. Under some conditions, it behaves as a liquid, while under other conditions, it acts as a solid. If you punch the mixture, it will be like hitting a wall, yet you can sink your feet or body into it like water. If you squeeze it, it feels firm, yet when you release the…
