Make+a+Huge+Soap+Bubble

Soap bubbles are easy to make and don't need a special kit. All you need to make a regular sized soap bubble is some liquid dish detergent and some wire that you've bent into a hoop. Dip it into the soap and blow. Simple!

Hugh soap bubbles are made on the same principle. Follow the directions below and astound your friends. Make huge soap bubbles outside. You might want to do this in your bathing suit.

To make a hugh soap bubble you need:
 * 3/4 cup dish soap
 * 1 teaspoon cooking oil
 * 1 bucket of warm water
 * 1 1/2 meter length of fuzzy absorbent string or wool

Directions:
 * 1) Tie the string into a circle.
 * 2) Lightly swish the dish soap and oil into the water.
 * 3) Soak the string in the bucket for 5 minutes.
 * 4) Lift the string out of the water with your hands, making sure they get wet with the mixture of soap and oil and water.
 * 5) Hold the circle out to your side and run slowly. If the string circle is too big for you to handle, ask a friend to help.
 * 6) Watch the bubble soar into the sky like a big balloon. If it pops, make another!
