Being that is was just July Fouth, and this model is awesome, here is how to make origami fireworks.
You will need:
1.) 15 square sheets of paper (whatever size/color you want. Bigger paper is easier to manipulate.)
2.) Scissors (To cut paper down to size.)
3.) Possibly some tape depending on how good you are with origami.
Step 1: Folding the Modules.
You can use whatever colors you want. I used red, green, yellow, and blue. Start off by folding the square in half diagonally. Unfold then fold on the other diagonal and unfold again. Fold in half longways and unfold. Cupboard fold to the center crease. Unfold. Fold two small strips on the top and bottom to where the diagonal creases and the outside vertical creases meet. Unfold. Fold the whole thing into a waterbomb base. Now fold the bottom up to the top and squash fold the sides so it looks like a little house. Repeat on back. Now fold up one of the little flaps on front and squash the side. repeat on all flaps and unfold. Congrats! You're done!!!......with the first module. 1 down, 14 more to go. Happy folding!
Step 2: Yes, 14 More.
Seriously. This could take a while. But it is well worth the wait!
Step 3: Connecting the Modules
Take two modules, slide the bottom flaps on one side of one onto the middle of the other one. Look closely at the pictures. Connect all the modules this way until you have a long, multicolored (if you are using many colors) caterpillar-like thing. Now go through the entire thing and re-squash all the little flaps and fold them over. Go back through and fold up all the flaps that you have just created.
Step 4: The Grand Finale!
Attach the two modules on the end to each other like you did with the rest. This can be kinda hard so this is where a small amount of tape comes in. Once you get those two attached YOU ARE DONE!!! (Really this time) Spin the sides and it looks like fireworks!!! I have no idea how it doesn't get tied up in knots! XD You could also use rainbow colors for a really cool effect
