Step 1: Materials
-A cereal box
-Duct tape (of any color)
-A hot glue gun
Step 2: Taping the Box Shut
Step 3: Measurements
Step 4: Cutting
Step 5: Side Access Opening
Trace and cut a square opening in the side of the box. It should be low enough for the bottom of the box to be right below it, and big enough to fit your hand through.
Step 6: The Internal Ramp.
To make the ramp, take the piece of cardboard that you cut from the front of the box, and cut it to get a piece that is the same width as the side of the box. Next, arrange it so it is no higher than than the lower wall of the box front opening, and is sloping down towards the access opening. Finally, hot glue it in place.
Step 7: Paper Stabilizers (Clothespins)
Take four clothespins, and arrange them on the box as shown, with the clipping part over the opening of the box front. Next, hot glue them in place.
Step 8: Covering
Simply cover all parts of the box in duct tape except the clipping ends of the clothespins.
Step 9: Access Opening Cover
Simply take the piece you cut to make.the access opening, and cover it in duct tape. Next, tape it at the top to the top of the access opening. You may find it necessary to cur a finger hold to make opening the cover easier.
The reason we did not simply leave the top part uncut was because the tape connection is much sturdier than a pure cardboard connection.
Step 10: Stand
Take the other half of the piece from the front cover, and cover it in duct tape. Next, bend it at approximately the angle shown (a little more than halfway). Then, tape it to the center bottom of the back of the box. Test to make sure the box stands up.
Step 11: Targets
Take a piece of paper and cut it to the same width as the box. Next, draw a series of concentric circles to create a bullseye target. Then, place the target in the clothespins. Repeat as many times as you want to get the desired amount of target papers.
