How Do I Tie a water balloon?

Make sure to leave enough air space at the open end of the balloon first of all.  Then, pinch off that end and twist it to hold the water in.  Wrap the open end of the balloon over your finger and pull through to make a standard knot.  Have fun!

I did this once. It's a bit of a challenge, but works VERY well. Build a "hexagonal" cage around the egg using drinking straws. Try to use smaller straws (girth) as building is much easier. Using hot glue, have the straws criss-cross in such a way to cradle the egg. You should wind up with something almost spherical.

From the link below:\n\n1. Hold one end of each shoelace in each hand.\n2. Cross them, making an X.\n3. Pass one end of the shoelace under the other.\n4. Pull tight.\n5. Fold one shoelace in half while holding laces taut.\n6. Wrap the other end around the folded end.\n7. Grasp it in the middle after pulling it around the folded end.\n8. Bend it into a flat loop and pull through, making a bow.\n9. Repeat with other shoe.

You will need the following materials: \n\n• balloons \n• long wooden or metal skewers \n• petroleum jelly \n• a sharp pin \n• cellophane tape \n\nBlow up a balloon – not too full – and tie the opening shut. Dip the tip of a skewer in Vaseline and spread the Vaseline along the entire length of the skewer. If you are careful, you should be able to push the skewer all the way through the balloon without popping it. Insert the skewer with a gentle twisting motion into the end of the balloon opposite the knot. Continue pushing and twisting the skewer until the tip emerges from the other end, near the knot. Why doesn't the balloon pop? \n\nNow try to stick the skewer into the side of the balloon.What happens?\n\nThe rubber in the balloon consists of many long molecules that are linked together. It's similar to the way all of the noodles in a plate of spaghetti stick together. These long molecules are called polymers; when molecules of a polymer are chemically attached to each other, it is called cross-linking. These links hold the polymer molecules together and allow them to stretch…up to a point. When the force or tension pulling on the cross-links is too great, they will break, and the polymer will pull apart. \n\nLook at the rubber near the ends of the balloon where you first inserted the skewer. Does it look lighter or darker than the rubber in the rest of the balloon? \n\nThe rubber at the ends of the balloon is stretched out less than in the middle of the balloon. Therefore, there is less force pulling on it. This allows the tip of the skewer to break some polymer cross-links, push aside the molecules of rubber, and slide into the balloon. However, enough cross-links remain so that the balloon holds together.\n\n\nIn the side of the balloon, there are fewer polymer molecules. When you push the tip of the skewer through the rubber in the side of the balloon and the skewer breaks a few of the cross-links, the tension on the remaining cross-links is too great, and the balloon pops. \n\nDo you think there is a way to stick a sharp pin through the side of a balloon without popping it? \n\nPut a small piece of cellophane tape on the side of the balloon and press it down well. Now take the pin and press it through the tape and into the balloon. Does the balloon pop? \n\nThe tape sticks to the rubber in the balloon and will not allow the rubber to stretch to the breaking point when the pin pierces the balloon. In other words, the tape reinforces the cross links, and the balloon stays together.

u can  take rod shaped plastic pipe of different sizes & pingpong balls at sides. cover them with clay to give them shape of a bone, then use  thin elastic rubber ( which are used in rubber band, thin white in color) use many of them  as muscle fibre by attaching them to bone

Probably the simpliest way I can think of is just to strap the balloon to a set of wheels and position it so that the opening is point in the opposite direction you want the car to move.  When the balloon is released, the air can escape out the hole and propell the car forward.

hello friend!\n\nuse a non-flexible thread. tie a simple knot first. roll the thread at the balloon stout for 3 times. then again tie a knot. again roll it for 3 times and then tie two knots. trust me! this would work! it wont leak a bit even if u leave it for a night!!!\nhappy fighting!!

fill water balloons with different amounts of water and drop them at the same height to see if they fall differently.  =)

tie a rope to a pole, both ends\nwhen ya see em gallopin thataway, em wont be overridin no more ya see

one option is to freeze the water, shape it into a concave lens shape, polish it till its transparent, and use the disk like a magnifying glass on the match head.\n\ni saw this actually done on myth busters, although it didn't go very well

put ur curson on it, drag it to to the bottom

Everyone must drop a egg from a height and not break the egg. All you can use is rubberbands and straws. So you cover the egg with straws (2 or 3 layers) and tie the ends with the rubberbands .

Very very simple. Take a baloon ( white or any light color), blow it to its complete size. Then, tie it at the end so that the air does not go out of the baloon. Then paint on it as the planet should be. Par example, Paint with blue and brown for the planet Earth. If you want to hang it, use a wire.

Assuming it is for a toy/model.\n\nThe only consideration is to make sure all of the lines are tied so the load hands level and does not cause the parachute to tilt.\n\nFor a dead load like (say) a square block I would tie them all to a central point on the top (and secure knot will do).\n\nFor a more human load (e.g. an action figure) you would be best to tie the right hand 6 to one shoulder and the other 6 to the other (like a normal parachute) - I would tie a string loop under the armpit and over the shoulder on each side (possibly with a string between them to stop them slipping).  The 6 strings on each side can be simply knotted to these loops.  This is pretty much how a parachute is fixed in real life although it is more of a complete harness.\n\nI hope that helps but if you need more info drop me a note.\n\n=8-)

Take the 2 strings and cross them to make an X. Take one of the strings and loop it under the ^ shape. Pull. Take one string to make a loop and hold w/ your fingers. Take the other string and wrap it around the loop. Then take the middle of the second string and pull it up inside the "wraped" part. \n It is easier learning to tie your shoes visually.

put the opening of the balloon on the spigot of the helium tank.  they are usually made of rubber.  when you tip the spigot to one side, helium comes out.

Ok. this is simple. u need to know about buyoancy, like how air is lighter than water. all you really got do is put some small weights (ex. paper clips, rocks, etc) in the bottle. have it so that it will just barely float. then cut a hole to the side and insert the end of a tube in it. make sure it is water tight. then place it in a tub. it shold float, when you suck on the end of the tube, it should take some of the air out making it less buoyant, and therefore it will sink. there are also many other ways to do this that will make it function more like a real submarine like putting the bottle with weights inside and somehow add pressure to the the outside of the tube to compact the air inside the bottle, causing it to sink. good luck on your project
