Supplies: a balloon and an air pump.
Making a crown using just one balloon has been my personal challenge for many years. I made it! In the following instruction you will see how I do it. But first, try to make one balloon crown on your own before you take a look on the instructions. Maybe you will find a better solution! Or at least you will appreciate more my work :)
Inflate a balloon leaving about 6 cm flat tail (pic 1 and 2).
Twist the first about 2 cm bubble (pic 3).
Twist the second about 4 cm bubble. Twist the third about 2 cm bubble. Twist the fourth about 6 cm bubble. Twist the fifth about 2 cm bubble. Twist the sixth about 4 cm bubble (pic 4). The first, the third and the fifth bubbles should be of the same size. And also, the second and the sixth bubbles should be of the same size.
Lock both ends of the first bubble in one lock twist (pic 5).
Lock both ends of the third bubble in one lock twist (pic 6).
Lock both ends of the fifth bubble in one lock twist (pic 7). Notice: I purposely lock both ends of the first, the third and the fifth bubbles only after I made the sixth bubble. This way I preserve flat tail necessary to make eight more bubbles :)
Wrap the balloon around your head to measure the size of the crown. Hold the balloon at the spot where it touches with the first bubble (pic 8).
Twist the seventh bubble at the mark (pic 9).
Lock both ends of the chain of the first seven bubbles in one lock twist (pic 10). We have made the base of the crown.
Make sure it fits you (pic 11).
Twist the eighth and the ninth about 4 - 5 cm bubbles (pic 12).
Lock the free end of the ninth bubble with the third bubble (pic 13).
All following bubbles we are going to twist starting from the opposite (the nipple) end of the balloon! Squeeze the rest of the balloon forcing the air to the end of the balloon (pic 14).
Twist the tenth about 2 cm bubble at the very end of the balloon. It should be about the same size as the first bubble (pic 15).
Twist the eleventh and the twelfth bubbles of the same size as the eighth and the ninth bubbles (pic 16 and 17).
Spit the rest of the balloon on two bubbles (the thirteenth and the fourteenth) of the same size (pic 18).
Lock the tenths bubble (the last small bubble at the end of the balloon) between the sixth and the seventh bubbles (pic 19).
Lock the fifth bubble between the twelfth and the thirteenth bubbles (pic 20 and 21).
Fix all bubbles in proper positions. Congratulations! You have made one balloon crown (pic 22 through 29). Working with different color balloons of the same brand you will notice the difference in the size of inflated balloons. Have no fear - you can make one balloon crown out of any color balloon! Of cause it would take some practice to handle shorter balloons. It helps if you twist each bubble no more than 2 turns instead of 3 or more. Have fun and happy twisting :)
