ARE YOU PRONE TO SKIP A STONE? WELL I'M GOING TO GIVE YOU SOME TIPS TO SKIP. . . .

Did you know that in England this sport is called ducks and drakes

For other cool stone skipping facts this website includes the stone skipping glossary and an audio interview. Also, I'm in the second paragraph.

Here's a website like the one above only its in Pennsylvania.

BEING THE SKIPPER......

To be a champ stone skipper you have to work at it and to do that you need to practice, practice, practice.....and then some more practice! Follow these few easy steps to begin your journey:

1. To even practice your first need two ingredients...water and stones.
2. Finding water: Pack up your hunting gear and go to the rockiest bank of water you know.
3. Selecting your stones: Walk along the banks looking for at first circular stone that are bought the size of the palm of your hand. Unearth the stones and examine the flatness of them. If they are flat, round and fit in your hand... then you have found your first stone!
4. Filling your bag: Good stones are precious and not to be wasted so fill your bag because you can only skip stone once.
5. You are ready to make your first skip.
6. 
7. The art of skipping: Skipping stones is not just throwing stones into the water. You have to put spin on it and throw it at the right angle(the perfect angle is not allowed.) First of all the techniques you have to firmly grip the stone with your index finger of the top edge and your thumb resting on the middle. Your ring and pinkie finger should be hanging underneath. The illustration below is a diagram of what it should look like before you grip the stone.
8. 
9. At the waters edge: When you get to the waters edge, step into the water (optional) up to a little above your ankles. This allows you to be one with the water. You can feel the ripples of the waves.( if there is any) Find the smooth area and......
10. Throwing the stone: Now, get into your grip and swing your arm forward getting up momentum as you release the stone. At the point when your about to release it flick your wrist giving the stone a rotational spin.
11. Counting your skips: If your a great skipper like some your stone will be easy to track because it will travel far just normally skipping. For beginners yours could gerplunk or could skip with a few pitty-pats.(visit website with stone skipping dictionary for definitions)

Finally, after a lot of practice and a whole bunch of self-esteem your ready to enter a contest. GOOD LUCK!

The Science of Stone Skipping......

For this i contacted Prof. Felczan, from the Wyoming high school and he gave me information about the physics of stones.

Q: Why do stones actually skip and not sink?

• A: "Balancing forces"

• "The origin of the force that causes a skipping stone to bounce is easy to identify. The conservation of momentum dictates that as the stone enters the water and pushes some of it downwards, the stone is, in turn, forced upwards. This force is equal to the hydrodynamic pressure on the stone multiplied by its area, which, using dimensional analysis, can be shown to scales as ρU²S, where ρ is the density of the water, U is the stone's velocity and S is its cross-sectional area. Assuming that this force is balanced against the weight of the stone Mg, where M is its mass and g is the acceleration due to gravity, there exists a minimum velocity - of the order of a few kilometers per hour - above which the stone will bounce" is how this website explains it.

Here's another website with a little different info.

Q: How can you make your skip better?

A: Speed

• To get a farther skip you actually have to throw the stone faster. This is because If you just throw the stone normal it flattens down onto the surface of the water quickly causing it to sink. This proves that the stone actually doesn't slow down it flattens and sinks. If you throw the stone at the water between a 10-20 degree angle at the water at as fast as you can you should be able to skip about a 20.

MAKING THE PERFECT STONE. . . .

I contacted Prof. Felczan at the Wyoming high school for the project and info.

• To make the perfect skipping stone Prof. Felczan thinks that if you create a dip in the bottom of the stone for an air pocket it will bounce more giving you more skips.
• 
• In his lab we tried to melt an air pocket in with hydrochloric acid and figured out that that acid doesn't affect the types of rocks that I skip. It only affects limestone.
  
• After a lot of thinking we found that if you really could make an air pocket the effect would be like a Frisbee thrown over the water until gravity pulled it down. This means that the stone would fly better giving it a better chance of breaking your old record.

This concludes my project and I think you are now ready to go skip.

PS. Here's some words is other cool languages.

Make a Splash ..... Skip a stone! ..... It's all good!

translates to ....

Italia; Faccia una spruzzata ..... saltare una pietra!


Russo; Сделайте выплеск прыгнуть камень!


Deutch; Lassen Sie ein Spritzen einen Stein überspringen!


Dutch; Make om Splash Skip heeft stone!


French; Faites sensation sauter une pierre !
