Kissing Apples

Kissing apples cover

What you need:Kissing apples
• Two apples
• String

What you do:
• Attach a piece of sting to each apple.
• Have each hand hold one string so that the apples  are at nose-level, 6″ apart.
• Blow hard between the apples and watch them move!

What should happen:
• The apples will get closer  to each other.

Why does that happen:
• The air pressure is lowered as you blow between the apples (think of the air molecules as ping pong balls … they balls don’t have enough time to touch the apple surface as they zoom by).
• The air surrounding the apples that’s not really moving is now at a higher pressure, and pushes the apples together.

Air Pressure

air pressure cover

What you need:Air pressure1
• An empty bottle
• Foil

What you do:
• Roll up  a pea size ball out of foil.
• Place the bottle on the edge of a table.
• Put the ball of foil inside of the bottle neck.
• Try to blow the ball into the bottle.

What should happen:
• The foil ball shoots back out towards you.

Why does it happen:Air pressure2
•The same principles that keep airplanes in the sky also apply to this  experiment. The key point is that moving air is at a lower pressure than still air. This is the Bernoulli Principle. In the case of the  bottle the air that is blown towards the mouth is deflected around the the sides of the bottle (very little moves past the ball of foil). This means that the air pressure in front of the ball is lower than behind, and so the ball flies out.
Airplane wings are specially shaped so that air travels faster over the top of the wing than over the bottom surface. Again the pressure is lower above than below and the wing is “pushed” upward by the higher pressure air – called lift. The faster the plane moves forward the bigger the lift it experiences.

• Paper to put the candle on

What you do:
• Draw a spider web on the candle by pushing the pencil into the wax.
• Trace the design several times with the pencil applying pressure.
• Wipe the candle with the alcohol wipe to get rid of the extra wax.
• Using your finger dab some toothpaste over your web design.

Water Barometer

Water barometer

What you need:Water barometer experiment
• glass or jar
• bowl
• 3 coins
• pen
• water

What you do:
• Fill the glass about two-thirds full with water.
• Place the bowl upside down over the glass.
• Carefully turn the bowl and the glass over so that the glass sits upside down in the bowl.
• Some of the water will run out of the glass but most will stay inside it.
• Slide the coins under the rim of the glass and space them equally around the rim.
• With a pen mark the level of the water in the glass at the beginning of the activity.
• Take your barometer outside into the open air.
• Look for changes in the water level in the glass over time. (This may take several hours or even longer than a day.)

How it works: When the atmospheric pressure of the air rises, the water in the bowl will be forced downwards by the weight of the air on the water. This, in turn, will cause the water in the glass to rise. A barometer measures the weight of the amount of air between the surface of the earth (the water in the bowl) and the top of the atmosphere.

DIY Barometer

DIY Barometer

What you need:barometer
• Scissors
• Tape
• Balloon
• Jar
• Elastic rubber band
• Straw

What you do:
• Cut the balloon in half.
• Discard the piece with the neck on it.
• Take the remaining piece of the balloon and stretch it across the glass or jar.
• Keep it stretched firmly across and seal it down with the rubber band, around the rim of the glass jar.
• Tape the straw onto the balloon lid; the straw should be sitting one quarter of a way on the lid, with the tape about 1 inch from the edge of the straw end that is sitting on the balloon lid. The straw is your indicator “needle”.
• Trim the straw if it’s too long, but leave more length off the jar as what is attached to it.
• Put the finished glass jar next to a wall and tape a piece of paper or card to the wall behind it.
• Mark the current position of the straw on the paper, and mark one above and below the mark, about the same length away, and label the high and low pressure.
• Check the straw regularly and keep marking its location on the paper for a few days.

Money Science

burn money

What you need:Burn Money1
• 2 TB spoons rubbing alcohol
• 1 TB spoon water
• tongs
• safety glasses
• fire extinguisher
• money

What you do:
• Start by preparing a water-alcohol mixture by combining 2 Tb spoons of 70% rubbing alcohol with 1 TB spoon  of water. Make sure to stir the mixture thoroughly.
• Dip a dollar  bill  into the mixture of water and rubbing alcohol, making sure the bill is completely soaked.
• Remove the bill using the tongs – squeeze out any excess liquid.
• Move the water-alcohol mixture to a safe place (away from the area where you are going to light the bill).
• Hold one end of the bill with tongs and light the bottom of the bill.
• The bill will look like it’s burning.
• When the flame is completely extinguished, it’s safe to touch the money… you’ll find that the money is even cool to the touch.



Crusoe’s Science

Crusoe's Science

Robinson science3If you got stuck on an uninhabited island like Robinson Crusoe you will need to know how to get salt for cooking and drinking water for survival.
So, here you go:

What you need:Robinson science1
• large bowl
• short glass or cup
• tape
• plastic wrap
• small rock
• pitcher of water
• salt
• long spoon for stirring

What you do:
• Make saltwater by adding salt to fresh water.
• Stir the water until the salt dissolves.
• Pour about two inches of saltwater in a large bowl.
• Take an empty glass and put it in the bowl. The top of the glass should be shorter than the top of the bowl, but higher than the saltwater.
• Put plastic wrap over the top of the bowl. You may need to use tape to make sure the seal is tight.
• Put small rock right in the center of the plastic wrap, over the empty glass. That will weigh the plastic down and help you collect the water. Now you’ve made a solar still. It’s called a still because it distills, or purifies, water.
• Leave your still outside in the sun.
• Leave it alone for a few hours, or even a whole day. The longer you leave it out, the more water you’ll collect.
• When you’re ready to check your still, take the plastic wrap off and look at the water that’s collected in the cup. Do you think it’s salty or fresh?
• Taste it.

Robinson science2

Tip: Rays from the sun heat up the salty water in the bowl. When the water gets warm, it evaporates and becomes a gas. When the gas rises and hits the plastic wrap, it turns back into water droplets. Eventually, gravity makes the water droplets roll down the plastic wrap towards the rock. Then the water droplets slide off the plastic wrap into the glass. The salt doesn’t evaporate, so it gets left behind in the bowl. Water evaporates in the same way from lakes, rivers, and oceans. The water heats up, turns into a gas, and then condenses to fall back down as rain.
