1. Blow balloons of the same size. Tie the blown balloons together, pink and pink, purple and purple.
2. Press the pink balloon pair and the purple balloon pair, and then wrap a pink ball and a purple ball around it.
3. Go around again.
4. This group of four balloons is completed, which is the basis of making balloon chain.
5. Prepare a long nylon rope or fishing line and wrap it around the hook (or door handle).
6. Put the balloon group on the rope from top to bottom, and then use the rope to bypass the pink ball and purple ball twice, so that the balloon is fixed.
7. Take out another balloon group, stagger it with the previous balloon group, hold it by hand, then wrap two balls in the two groups of balloons once with a rope, and then wrap two balls in the outer group twice.
8. If this goes on, it will be made into a balloon chain, which can be hung indoors and outdoors as decoration. If you make a balloon arch, it is usually 5 meters long.
9. Prepare an aluminum-plastic PVC pipe, which can be bent at will and pressed into the balloon chain.
10. Prepare a welding base. If there is no such base, it can also be made of cement. The specific method is: put some cement in a small round paint bucket with no bottom, and then insert a pipe into the cement. When it takes shape quickly, pull out the pipe, take off the bucket and let it dry naturally, which is a bit like making honeycomb briquette.
1 1. Insert the balloon chain that has just been equipped with pipes into the base, so that the balloon arch is completed.
