Instructions =========== Step 1 - Gather two ping pong balls, and cut two pieces of string that is 2 feet in length or longer (length will depend on where you are hanging the string from)
Step 2 - Tape one end of one piece of string to the first ping pong ball. Tape one end of the other piece of string to the second ping pong ball.
Step 3 - Hang the other end of the string to a stationary object. The objective is for the ping pong balls to hang freely in the air at the same level and about 4 inches apart.
Helpful Tip: We used a clothes drying rack. You could also tape them to a door frame or hand them to a shower curtain rod.
Step 4 - Make sure the ping pong balls hang in mid air at the same height about 4 inches apart.
Step 5 - Use a drinking straw to blow air directly in between the ping pong balls. What happens to the ping pong balls when you do this?
Items Needed =========== * Small clear glass bottle with narrow mouth * Large clear contains that is at least 5 inches taller than the bottle) * 3 ft of String * Food Coloring * Hot Water * Cold Water
Instructions =========== Step 1 - 4: Begin with a small glass jar with a narrow mouth. Cut a long piece of string (3 ft) and tie one end around the mouth of the jar. Then thread the other end through the piece of string on the other side of the mouth of the jar. Tie that end into a knot. Ensure that both knots are tight and cut off any excess from the ends of the string.
Once you have finished, you have created a string handle that you will use to pick up and lower the jar.
Step 5: Next pour hot water into the jar. Helpful Tip: Use a funnel to make it easier to pour the water.
Step 6: Add a 5-10 drops of red food coloring to the jar. The water should be a dark red color.
Step 7: Next get a large clear container and fill it with cold water. Helpful Tip: The container must be taller than the bottle. For best results, the water level should be 4-5 inches higher than the top of the bottle.
Step 8: Carefully pick up the bottle using the string handle you created and slowly lower it into the container of water. Observe what happens next.

Items Needed =========== Large Empty Clear Jar 2 Cups of Water 1 Cup Vegetable Oil 4 Tablespoons of Salt
Instructions =========== Step 1 - Begin by fulling a large jar about halfway full of water Step 2 - Next, add a cup of vegetable oil to the jar. Wait 30 seconds for the oil to completely separates from the water. Step 3 - Add a heaping tablespoon of salt to the jar and watch what happens.
Items Needed =========== Small Ball Jar with a mouth that is larger than the ball
Instructions =========== 1 - Gather a small ball and a jar with a mouth that is bigger than the ball. Bouncy balls are great for this experiment, as are pint sized canning jars.
2 - First attempt the pick up the ball using the jar. You notice that it is difficult to do so, but you may be able to figure out the experiment with a little trial an error.
3 - If you can't pick up the ball, start again. This time place the jar over the ball on a hard surface.
4 - Next, begin to move the jar in circular motions around the ball. The ball will eventually begin moving along the rim of the jar. As this happens, begin moving the jar faster and faster until the ball moves up into the jar. Helpful Tip: This step will take practice and patience, but if you take your time you will eventually get the ball to move up into the glass.
5 - Continue moving the jar in a circular motion and lift it off the table. You have just successfully picked up the bar, using just the jar. Helpful Tip: While this experiment looks easy to perform, it does take practice to get it down. Don't get discouraged if you can't do it the first time. Instead keep practicing and you will eventually be able to pick up the ball.
Items Needed =========== * Drinking Glass * Water * Think Sheet of Paper that is long and wide enough to cover the entire mouth of the glass. (We used a piece of poster board) * Large Container or Sink
Instructions =========== * Step 1 - Begin by filling the empty glass with water. Helpful Tip: Ensure that the water is completely to the top of the glass. If there is any space between the water and the paper, the experiment won't work. * Step 2 - Gently place the paper on the top of the glass. * Step 3 - Move the glass over the container or sink. * Step 4 - Gently place your hand on the paper, then flip the glass over. * Step 5 - Remove your hand from the bottom and watch in amazement as the paper stays covering the glass and the water doesn't spill out.
Items Needed =========== Set of Glasses of equal shape and size Water Metal Spoon Food Coloring (optional)
Instructions =========== * Begin with empty glass jars of the same shape and size. Use the metal spoon to tap on each one. You'll notice that each sound is the same. Now let's find out if we can make the sounds different. * Pour water into each jar. Make sure that the water level is different in each jar. * Add food coloring to each jar to make it easier to see the different water levels. You can use the same color in each jar or use a rainbow of colors like we did. (Optional) * Use the same metal spoon to tap on the jars again. Listen carefully so you can hear how the sounds have changed.
Items Needed =========== Large Bucket or Container Water Unopened Pop Cans (use a variety of pop, some regular and some diet)
Instructions =========== 1 - Begin by filling a large container with water. The water should be deep enough so you can easily tell which cans are floating and sinking. 2 - Slowly and place each can into the water one at a time. Make sure to tip the can on it's side when you are placing it in the water so no air is trapped at the bottom of the can. 3 - Observe the cans. Which ones floating? Which ones sink?
Items Needed =========== Water Clear Glass Clear Bowl Pitcher Blue Food Coloring Yellow Food Coloring
Instructions =========== Pour water into an empty glass until it is 3/4 of the way full Add 1-2 drops of blue food coloring to the water and stir until combined Fill a pitcher full of water. Add 7-10 drops of yellow food coloring to the water and stir until combined. Get a large empty bowl and place the glass with the blue water in the center of the bowl. Next, pour the yellow water from the pitcher into the bowl. Be careful not to get any water into the glass. What do you see when you look through the bowl? Is the water in the bowl yellow? What about the water in the glass? Why is some of the water green?
Items Needed =========== * Two Oranges (We used Clementines, but any orange will work) * Two Glasses or Containers (Note: They must be big enough to put an orange into) * Water
Instructions =========== Step 1 - Begin with two empty glasses or containers. (Note: They must be big enough to put an orange into)
Step 2 - Fill each container 3/4 of the way full with water.
Step 3 - Slowly and carefully place an orange in one of the containers. What happens to the orange? Does it float or does it sink?
Step 4 - Next, remove the peel from the second orange.
Step 5 - Slowly and carefully place the peeled orange in the second container. What happens to this orange? Does it float or sink?
Items Needed =========== 3-5 Paperclips (even more if you want to see how long of a chain you can make) Magnet (Ceramic Round Disc Magnets or Ceramic Bar Magnets work best)
Instructions =========== Begin by trying to get the paperclips to stick together to form a chain. Do this put holding one paperclip and then putting another next to it. You'll notice that when you let go the paperclip falls to the table. There is no way to get the paperclips to stick together...unless we add another item.
Next, take a magnet and place one paperclip on it. Helpful Tip: The stronger the magnet, the more paperclips you will be able to stick together. We used Ceramic Round Disc Magnets and put 5 together to form our magnet. Another option is to use a Ceramic Bar Magnet.
Next, slowly add a second paperclip to the bottom of the first one. Take your time on this one because the magnetic force will want to pull the second paperclip up to the magnet, but if you are patient, you can get it to balance at the end of the first paperclip.
Once you have two paperclips stick together, try to add another and then another, until you've formed a long paperclip chain.
Add a fun twist and remove the paperclip chain from the magnet. To do this, pinch and hold the first paperclip, then slowly pull the magnet away. Then watch in amazement as the paperclip chain stays together.
Items Needed =========== Empty Glass or Bowl 5-6 Pieces of Ice 1/2 Cup Water Piece of String 1/2 Teaspoon Salt
Instructions =========== Put 5-6 pieces of ice into an empty glass or bowl. Next, add the water into the glass. Try to use the string to pick up a piece of ice. You will find that it isn't possible. Next, lay the piece of string over the ice. Sprinkle the salt over the string and wait for a minute. After a minute has passed, pick up the string and watch what happens.How Water Bends a Straw Science ExperimentCool Science Experiments Headquarters2015-12-21 | Sign up for Cool Science Experiments FREE Weekly Newsletter: http://coolscienceexperimentshq.com/subscribe
