Hello Crafty Friends! Today I’m excited to share a new explosion box craft with you – this time for Valentine’s Day! What is an explosion box? When the lid is lifted off of the box, all four sides fall down revealing what is inside! It’s an exciting, unexpected surprise making them so much fun to gift. 

I designed this explosion box after seeing how much my family and friends liked my Christmas Explosion box. For this Valentine’s Day version, each of the sides has a place to feature pictures and notes. This makes it perfect for gifting to friends, besties, daughters and even significant others. 

There is a small box at the center of the explosion box that is perfect for holding sweets and small gifts!

Christmas Explosion Box

Supplies Needed

Two paper stacks by American Crafts lay on a white surface.

A group of colorful paper peices of paper on a white surface.

Assemble the Box

Step One: Adhere the white colorful squares of paper to the inside of each box side. I used 1/4″ Scor-Tape around the edges of each square. This was thin enough to not show through any of the holes.

The colorful squares of paper are applied to each side of the explosion box.

Create the Mini Interior Box

Step Two: Create the box that is at the center of the explosion box. Fold the flaps along the score lines on both the box bottom and box lid. Add adhesive to the tabs and to the outer edges of the pink square. Place the pink square behind the lid cut out, then form the box and lid by attaching the tabs.

The back of the mini box is covered in strips of double-sided tape.

Create the Bow

Step Three: Create a paper bow for the top of the box. Start by rolling the loops of the bow with a pencil to help them form without creating hard creases. Place adhesive in the center and secure the loops to the center of the bow. Wrap the small rectangular piece of paper around the center of the bow, then attach the bow flaps to the underside of the bow.

Create the Box Lid

Step Four: Fold the box lid along the fold lines then place adhesive on the flaps and form the lid. Fold the ribbon piece along the score lines, then secure it to the box lid. Add the bow to the center of the lid.

The paper ribbon and bow are attached to the top of the box lid.

The lid is complete! Lift up the side flaps of the box and place the box lid on top to hold them in place. When the lid is lifted up, the sides of the box will fall down!
