Slowly, pull the straw all of the way out of the bubble. Touch the straw to the lid and blow a bubble on the lid.Dip a straw into the container of Homemade Bubble Solution getting half of the straw completely wet.Fill the lid with Homemade Bubble Solution. Set a lid on your table with the lip facing up.Slowly, blow a bubble through it until the bubble comes loose from the wand. Dip the bubble blower into your Homemade Bubble Solution.Using a second pipe cleaner, fold it in half and loop it around one sdie of the other pipe cleaner square.Wrap the ends around the sides of the square to hold it together.This allowed the bubbles to hold their shape when you blew into your bubble wand. This made the water become flexible and appear elastic. When you made bubbles, you added soap to the wter. In plain water, the surface tension is strong and the water might make some bubbles but they will be small and won't last for very long because the other molecules in the water will pull on the bubbles and flatten them. The force of surface tension also created bubbles. What happened when you put your soapy finger into the water? The soap broke the water's surface tension and some of the water molecules stopped sticking to each other causing them to be pushed out of the glass. Surface tension is what caused the water to rise up above the rim of the glass in the experiment and form a dome instead of spilling over the side. At the top of the water, the molecules stick together very closely to make a force called surface tension. In this activity, the water molecules are attracted to each other and stick together. An atom is the smallest piece of a chemical element that is still that element. ![]() A molecule is two or more atoms bonded together. What happens this time?īefore we begin, let's define molecule. ![]()
