I have been thinking about ways to modify this structure and came up with two variations. One is inspired by Valentine's Day and the other is the answer to the question: What happens if I make a smaller version and nest it inside the bigger one? I hope you like the results and try folding one yourself.
Stages of folding the structure.
Two orientations of the round structure. There are more below.
I cut out hearts from paper folded into the water bomb base.
Variation 1: Insert hearts cut from 4 x 4 inch paper into the slots to make a unique Valentine.
Variation 2: Fold a second structure from 3 x 18 inch paper and nest it inside the 4 x 24 structure.
Three ways to twist the structure.
