This is a homemade dart that can be made in abut 5 minutes.

Step 1: Suplies and Tools

Here is what you'll need.
1.Pencil
2.Tape, preferably duck tape
3.Glue
4.Small Screw
5.Some thin foam, can be found at craft stores
6.Hammer
7.Small scissors and/or small knife
Okay, lets start.

Step 2: The Main Body

Okay, take your pencil and with some pliers, or if you want, your teeth, and take off the eraser. Make sure that you get the metal thing too. Once it is off, discard the metal piece and the eraser. Now, take the small knife and split the pencil(see photo). Now take the knife and cut a nick about half an inch from the end in the split part on the pencil(photo). Be careful, as it can break easily.

Step 3: The Tip

Take your screw, and with the hammer, pound the flat end in a rectangle shape. If your nick was the right size, your screw should now fit right into the nick. Take the tape, and warp it around the screw and pencil a few times. Leave enough screw(see photo, dont mind the purple thing) so that while the screw is secure, it can also stick into that carbord box, a cat, or your sister. Joking of course.

Step 4: The Tail

Okay, take your foam and cut a circle with you sisors about 1 1/3 inches tall/wide. Cut a hole in the middle, thiner than the pencil.
cut lines in the foam a 1/4 inch long. do this all the way around(see photo). Now cut two lines all the way to the hole(photo).
Staple the to edges together(photo). Now slide the tail on the end of the pencil where the earaser used to be. Gle it in place, and your done. Have fun and be safe.
