-Box cutter and scissors
-Glue or tape
*Ribbons, bows, etc (for decoration)
This box does not literally explode, it just falls open. Yeah, just killed all the excitement :[
Step 1: Cutting
Cut with a box cutter, your teeth, or a spoon if you have the skills.
Dimensions are vague because you can make this box any size imaginable, depending on how much cardboard you have.
Step 2: Wrapping
Step 3: X
You can adjust the size by trimming to how much you want the wrapping paper to be exposed.
Be sure that the middle square is the EXACT same size as one of the wrapped squares or else the sides will not fall correctly.
The image below should clarify.
Cut out the cross following the red lines.
After having the cross cut out, crease the gray lines(shown below).
Step 4: Coming Together
If everything is going well these should fold up and fall down.
Step 5: Cap It
The cap will just be the large wrapped square with some smaller rectangles added.
Take any cardboard scraps you have and cut out rectangles the length of the square and maybe 1 inch in height.
Make 4 of these rectangles. Then wrap each one individually with wrapping paper.
(You can line the insides of your rectangles and large square with the thick paper you had to match the box and hide showing cardboard)
Assemble the cap by taping or gluing each rectangle to the outside of the square. Hot glue works well here.
Fold up the flaps and top it off with a cap and you're good!
Step 6: Finish!
Well everything is complete now. The outcome is a multipurpose box. So gift it, put something in it, use it as decoration, anything.
Take your lunch in it, that can of Spam will work. Everyone will be envious when you pop that top. You may then proceed to take over the world with your can of Spam and your explosion box.
