Introduction: Zen Art With a Water Bottle

Recycle that water bottle, and make a cool sand art pendulum.

This is a nice project for the kids on a day when you can't go out and play. This entertained them for hours. But when you're all done, you WILL need to vacuum, and they WILL need to take a bath.

You will need:

a water bottle
string
scissors
a big piece of cardboard
salt or sugar (or sand)
a needle, or drill bit, or awl. (something to poke some holes.)

Step 1: Build Your Pendulum

Take an empty water bottle, and cut off the bottom. Poke three hole equally spaced about 1/4" from where you cut. Tie a sting to each hole. Tie strings together at the other end. All 3 strings should be the same length.

Now take the cap, and drill a hole through the top. (about 1/4" diameter)

Step 2: Hang It Up

Now hang your pendulum from something. We hung ours from our light fixture, but you can hang it from the ceiling, a door frame, or just hold it.
You can tie a string to the end of your 3 stings, to make it long enough. You'll want it about a foot or less above the table top. (or floor)

Step 3: Fill 'er Up

Now it's time to fill up the bottle. I used Salt. You can use sugar, but your little ones might spend more time eating it than playing. You could use sand if you had some.
Fill the bottle while holding your finger over the hole in the cap. Get ready to remove you finger and give it a good swing. (Not too hard, or you'll shoot salt across the room.)

Make sure the bottle is DRY. If there is any water in there, the salt with clump, and it will not flow out.

Step 4: Let It Swing.

Let is swing around. Give it a twist to make some interesting patterns. Let the little ones try to catch it, and send it off. If your little ones are bigger, go ahead and share all your knowlegde of pedulums, and Foucault pendulums..

Step 5: Do It Again.

Since you made your salt art on your handy cardboard, you can fold it, and pour the salt back into a cup. Then pour that salt back into the bottle and do it all over again. See how many different patterns you can get. Find out what happens when you swing hard, slow, with a twist, etc.

Step 6: Freestyler

Once you get sick of the pendulum, you can draw freestyle with the bottle. The kids have fun drawing in the salt with their hands. Combs make fun patterns too.

Hope you have lots of fun with this. Don't mind the mess, it's easy to clean. Now throw them in the bath, and wash off all that salt.

Spilling: The act of dropping or spreading out of a fluid or particles; The action of spreading out in the manner of a fluid Spilled: spilled - The amount of the material spilled, in gallons or pounds. The amount field often contains an estimate made at the time the spill is reported. Yeah i reckon it come under it, but in all truthfulness it is intentional spilling so we could let this one slide as "debatable, but not worth debating"

it was quite a shoddy argument to begin with, so I don't see why a shoddy person like you could possibly win such a shoddy argument.

It's a very shoddy term that depicts the shoddiness of the object of the sentence and also is a very shoddy term to use in an argument, as people tend to see it as shoddy. in other words, GOOGLE.

This is a really great idea, but I think it would be better to use play sand. If I'm not mistaken, it can be bought in small amounts at craft stores. That way, you're not wasting food, well, ingredients anyway.

I never heard of FSM before. Now that I know about it, I am intrigued. Who knew my piece of string that I was too lazy to cut down would be a sign.

Nice idea ! If you use heavy paper inside a shallow box, you can pick up the salt and slide it into the bottle, skipping the cup step and the shallow box (such as a lid from copy paper carton, helps to contain the salt. I used this method with glitter for decades. Also, Kosher salt is good because its more coarse than table salt and works a lot like sand. aren't nancy
