# Abdominal Inflation How To Blow Up

## How to inflate a helium balloon

Helium balloons are beautiful decorations for special occasions such as birthdays and other parties, as they solemnly float instead of falling to the ground. Filling balloons gives you several advantages. It's easier to transport uninflated balloons to a party location. You can fill up the tank and unfilled balloons on site before your party, making sure they last long enough! Plus, it's usually cheaper to inflate them yourself.

### Part one of four:With a helium tank

1. 1 Determine how much helium you need. Multiply the cubic feet of helium required for your balloon size by the number of balloons you want to fill. Since there are different balloon sizes and helium tank sizes, you can consult an online map to find out which tank size you want.
• For example, a standard size balloon, eleven inches tall, requires 0.50 cu. ft. of helium. A 50 cu. ft. helium tank can therefore fill 100 eleven inch balloons because 0.50 (amount of cubic feet required per balloon) x 100 (amount of balloons desired) = 50 (size of the tank in cubic feet).[1]
2. 2 Obtain a helium tank. You can buy or rent these from party stores. If you blow up lots of helium balloons often, consider buying one. But if that's a one-time deal, rent one instead. Party shops typically offer helium tanks that you can rent for up to three days. You may be able to negotiate for a longer period, or you can just go to one of the stores that offer longer term rentals.[2]
• Buying a tank of between eight and fourteen cubic feet of helium costs about \$ 40 to \$ 60. Helium tank rent ranges from about \$ 25 for 14 cubic feet of helium to just over \$ 200 for 291 cubic feet of helium (enough to fill about 525 11-inch balloons).
• Bring the item back to the store by the agreed time so you don't have to pay an additional fee. A security deposit may be required and a late return may result in a dock on your deposit.
3. 3 Decide when to fill the balloons. How long your balloons stay afloat depends on temperature, humidity and altitude. Generally, foil or "Mylar" balloons stay in the air for between two and fourteen days, while latex versions stay afloat for four to sixteen hours.
4. 4 Place the balloon valve over the helium tank nozzle. Rotate the inflator onto the nozzle by turning the inflator clockwise while looking at the tank.[3] Continue to screw in the inflator until it is secure.[4]
5. 5 Use the correct adapter. Attach the larger, cone-shaped adapter to latex balloons. For foil balloons, attach the smaller, screw-shaped adapter to the tip of the latex adapter. Make sure the appropriate adapter is connected to the inflator.[5]
6. 6 Open the publication. The tank should have a release button that resembles the faucet handle for a garden hose. Turn the knob counterclockwise.[6]

### Part two of four:Inflating a latex balloon

1. 1 Attach the balloon to the nozzle and release the helium. Roll the mouth of the balloon onto the nozzle a little. While holding the end of the balloon on the nozzle with one hand, press the nozzle with the other hand to release the helium. The balloon will inflate quickly, so be ready to remove it.[7]
• If nothing happens when you press the nozzle, try activating the helium by pressing the nozzle instead.
• Do not overfill the balloon. Latex balloons should have a round shape when inflated. Balloons in the shape of pears or lightbulbs are overcrowded and more likely to burst. They also use more helium so you get fewer filled balloons.
2. 2 Remove the balloon. Gradually let go of the nozzle when the balloon fills up. Squeeze the end of the balloon and slowly remove it from the valve. Tie a tight knot in the neck of the balloon.[8]
3. 3 Attach the tape if desired. Take a piece of ribbon and place it around the neck of the balloon, above the knot. If you want to curl the shorter end of the ribbon, leave a ribbon hanging from that end. The other end should be long. Tie a knot in the ribbon.[9]
• By tying the ribbon around the neck of the balloon instead of below the knot, the helium is given additional security against leaks, so that your balloon remains buoyant for longer.

### Part three of four:Inflate a foil balloon

1. 1 Fill the balloon through its valve. Find the opening on the tab at the end of the balloon. Slide the valve over the nozzle adapter until it is firmly seated. Hold the balloon tightly around the adapter and press down on the nozzle.[10]
• The balloon is finished inflated when most of the wrinkles have disappeared. Foil balloons do not expand, creating wrinkles. They will burst if you overcrowd them.
2. 2 Secure the flap. Foil balloons automatically seal so all you have to do is pinch the valve flat. Do not tie a ribbon around the valve or the neck of the balloon. This can lead to an air leak.[11]
3. 3 Add a long ribbon. Make sure you pass it through the tab or hole under the balloon valve. Make the ribbon long on one side and short on the other as you tie the knot. After that, you can curl the ribbon and add a sandbag.[12]
4. 4 Use the balloons if desired. Slide a long straw through the opening of the balloon. Gently push down until all of the air has left the balloon. Fold the balloon without folding it and save it.

### Part four of four:Arranging the balloons

1. 1 Choose a ribbon color and style. A good length for balloon ribbons is 48 to 57 inches (120 to 140 cm) per balloon.[13] You can match the ribbon color to the balloon color or go for a neutral color like ivory or white. The latter is usually used on formal occasions such as weddings and anniversaries.
2. 2 Curl band with scissors if desired. Use one hand to press the scissors blade against the blunt side of the tape. With the other hand, pull the length of the ribbon taut over the scissors blade in one long pull. Repeat if the ribbon does not curl on the first try.
3. 3 Place the balloons individually or in bundles. Placing balloons in very large or small clusters can reduce their impact. Consider arranging balloons in bundles of five to eight balloons each.
• You might want to mix up balloon colors, or even use bundles that contain both foil and helium balloons.
4. 4 Buy or make balloon weights. Buy balloon weights in party stores or discount stores. To make balloon weights, pour sand onto a sheet of mylar paper and secure it with a wavy tape.[14]
• To make your own balloon weights, cut sheets of metal paper up to twelve by twelve inches. One cup of sand should hold up to six balloons.
• When buying balloon weights from a party store, a member of staff should be able to tell you how many balloons their weights can hold. Alternately, consult a helium height and weight chart for balloons.[15]
