BOUNCING BUBBLE

WATCH THE VIDEO HERE

Materials

• 1 cup of distilled water (240 mL)
• 2 tablespoons of Dawn dish soap (30 mL)
• 1 tablespoon of glycerin (15 mL)
• Pair of inexpensive gloves
• Small bubble wand or pipette

EXPERIMENT

1. Make up a batch of Bouncing Bubble Solution with the ingredients listed above. Making your bubble solution at least 24 hours in advance and allowing it to sit undisturbed will allow the bonds in your bubble solution to strengthen. You know what that means, right? Stronger bubbles!
2. Using a small bubble wand, blow a bubble about the size of a baseball. If you are using the pipette instead of the bubble wand, cut the bulb off the top of the pipette, dip it into the bubble solution, and blow into the other end of the pipette.
3. Bounce the bubble off of your gloves. Try bouncing the bubble off of your shirt or pants. As you'll soon see, some fabrics work better than others.

About the Ingredients...

Water - The single most important part of the bubble solution is the water. Good quality water that does not contain high levels of iron or minerals is best. If you're uncertain as to the quality of your tap water, invest in a gallon of distilled water from the grocery store.

Soap - When it comes to soap, Dawn® dish soap just seems to work the best for homemade bubble solutions.

Glycerin - Glycerin is the secret additive that gives a bubble its extra strength. Don't be too shocked by the price on a bottleof high quality glycerin. Contact the pharmacist at your local grocery store for availability. (Note: Some bubble recipes substitute Karo® Syrup for glycerin due to the expense and availability of glycerin.)

Bubble Colors - Similar to the way we perceive the colors in a rainbow or an oil slick, we see the colors in a bubble through the reflection and the refraction of light waves off the inner and outer surfaces of the bubble wall. You can't color a bubble since its wall is only a few millionths of an inch thick. A bubble reflects color from its surroundings.

HOW DOES IT WORK?

The bouncing bubble is amazing because most people have never seen a bubble bounce! Experience tells us that regular bubbles burst when they come in contact with just about anything. Why? A bubble’s worst enemies are oil and dirt. A “super” bubble will bounce off of a surface if it is free of oil or dirt particles that would normally break down the soap film.

WATER BALLOON IN A BOTTLE

WATCH THE VIDEO HERE

Materials

• One liter bottle
• Duct tape
• Balloon
• Tack or pushpin
• Water

EXPERIMENT

1. Let's start by trying to blow up a balloon inside of a one liter bottle. No problem right? Put the balloon into the bottle, wrapping the open end around the mouth of the bottle.
2. Take a deep breath and blow up the balloon. You can't do it? Oh no! What's going on here?
3. We'll answer that question in a bit. For now, poke a hole in the bottom of the bottle using a tack or pushpin.
4. Take another deep breath (remember how hard… er… impossible it was to blow up the balloon last time) and try blowing up the balloon.
5. That was easy! While the balloon is still inflated, cover the hole in the bottom of the bottle with a finger and take your mouth off of the balloon. It stays inflated!
6. Take your finger off of the hole in the bottle and the balloon will deflate. Wow!
7. Now let's add some water.
8. Blow up the balloon and cover the hole in the bottle with a piece of duct tape. Make sure that the tape will be able to hold for a while.
9. Fill the blown up balloon with water and tie off the balloon. You've achieved the water balloon in a bottle.
10. You were promised a trick to play on your friends, so here you go!
11. Once you've blown up the balloon and filled it with water, leave the balloon open, and cover the hole in the bottom with your finger. Show a friend that you've successfully put a water balloon in a bottle. When they attempt to check whether or not there is water in the balloon, let your finger off of the hole in the bottle. The water blasts out and gets them all wet!

HOW DOES IT WORK?

The balloon won't inflate much the first time because the bottle is already filled with air. There's no room for the balloon to expand inside the bottle. However, when you punch a hole in the bottle, the air molecules in the bottle have an exit. They're pushed out as the balloon fills the space inside. As long as you plug the hole, the balloon stays inflated. When you take your thumb off the hole, outside air flows back into the bottle as the balloon collapses. Because of the elasticity of the rubber or latex, the balloon shrinks to its original size as the air rushes out the top of the bottle.

 

Suppose your thumb gets tired while the balloon is inflated. Put a cap tightly on the bottle and remove your thumb. For the air to flow, both holes have to be open. How would more holes or even one large hole change the speed of inflating and deflating the balloon? What would more or bigger holes do to the stream flowing from the water-balloon-bottle? Try it out! Balloons and bottles make a great science combo!

ANTIGRAVITY WATER

WATCH THE VIDEO HERE

Water in rivers, in a glass, or falling from clouds obeys gravity. It's going to fall towards the ground because of the physical pull of the earth. But, what if we told you that you could turn a glass of water completely upside down and the water wouldn't fall to the floor? That's what happens in the Anti-Gravity Water demonstration. It's a simple experiment that dramatically demonstrates the amazing physical properties of water. 

Materials

• Tall glass with a round edge
• A handkerchief
• A pitcher of water
• Bowl or sink

EXPERIMENT

1. Drape the handkerchief over the glass, making sure that you push the center of the handkerchief down into the glass. 
2. Fill the glass 3/4 full with water by pouring water into the middle of the handkerchief.
3. Slowly pull the handkerchief down the sides of the glass making it taut (stretched tightly across the surface of the glass). Grip the ends of the handkerchief at the bottom of the glass.
4. Place one hand over the mouth of the glass and turn it over with the other hand.
5. Pull the lower hand away from the glass (slowly) and the water should stay in the glass! This just goes to prove that the handkerchief has anti-gravity properties. The thunderous applause will drown out the cries of, "How did you do that?"
6. For the big finish, put your hand over the mouth of the glass and turn the glass right-side up. Remove the handkerchief from the glass and pour the water back into the pitcher. Of course, take your well-deserved bow.

HOW DOES IT WORK?

Most people predict that the water will leak through the holes in the handkerchief because the water leaked through the holes as it was poured into the glass. The holes in the handkerchief literally disappeared when the cloth was stretched tightly across the mouth of the glass. This action allowed the water molecules to bond to other water molecules, creating what is called surface tension. The water stays in the glass even though there are tiny holes in the handkerchief because the molecules of water are joined together to form a thin membrane between each opening in the cloth. Be careful not to tip the glass too much because you'll break the surface tension and surprise everyone with a gush of water!

Balloon Experiment

Supplies Needed:

• 2 balloons
• sweater
• assorted materials
  • tissue paper {we used 2 different sizes}
  • aluminum foil
  • cardboard scrap
  • paper scrap
  • yarn/string
  • pom pom
  • pipe cleaner
  • ribbon
  • cloth
  • foam

Procedure:

1. Gather a random assortment of materials. See the suggestions in the materials list.
2. Blow up the balloons.
3. Touch a balloon to each of different materials including the other balloon. {Notice none of the materials is attracted to the balloon.}
4. Rub one balloon onto the sweater. {This will add electrons to the balloon and cause it to become negatively charged.}
5. Now touch the balloon again to each of the materials. Observe what happens.

Questions to Ask: 

• What will happen when we touch the balloon to these objects?
• What happened when the balloon touched the tissue paper? {The tissue paper was picked up by the balloon. The tissue paper stuck to the balloon.

HOMEMADE ThERMOMETER

A homemade thermometer can be created from simple household materials and provides a reliable and accurate indication of changes in an environment's temperature. Heat and cold will affect the liquid in the homemade thermometer the same way temperature affects a thermometer filled with mercury. As the temperature around your homemade thermometer rises, so will the liquid inside. As the temperature drops, the liquid will drop as well.

Things You'll Need

• Clear plastic bottle
• Tap water
• Rubbing alcohol
• Clear drinking straw
• Red food coloring
• Modeling clay
• Permanent marker
• Traditional thermometer or thermostat

Instructions

1. • 1
     Fill 1/4 of the bottle with room-temperature tap water.
   • 2
     Pour rubbing alcohol into the bottle until it is half full.
   • 3
     Add a few drops of red food coloring to resemble mercury.
   • 4
     Place a small amount of modeling clay on one end of the straw, and put the other end of the straw in the bottle. Position the straw so that it does not touch the bottom of the bottle and affix the clay to the top of the bottle to hold the straw in place.
   • 5
     Put the bottle inside a container with hot water.
   • 6
     Observe how far up the straw the liquid has risen. If desired, use a permanent marker to draw a line on the bottle to indicate the current temperature. The exact temperature can be determined with a traditional thermometer or thermostat, then written on the bottle.
   • 7
     Now place tha bottle inside a container with cold water. The liquid will then contract and flow back down the straw to the bottom of the bottle.
