What can be handmade high-content high-tech works

1. First we cut out 6 to 8 leaf-shaped pieces of soft paper.

2. Fold them in half and glue their edges together to make a balloon.

3. Tape four strings to the bottom of the balloon. Use playdough to attach the other end of the strings to the table.

4. Turn the hairdryer on as slow as possible. Point the mouth of the hairdryer upwards towards the opening at the bottom and turn the switch on. The balloon will slowly get bigger and pull the string tight and off the table.
