things you will need:

• 0.25 foot of thin not stretchy string
• a hot glue gun
• a paper clip
• super glue
• 0.5 foot of filament

1. To make the expandable part cut about 10 mm of filament, touch the tip of the hot glue gun to filament creating a bulge in the end. Stick  the non-bulged end through both center holes of the two-part 1s. Now touch the non-bulged end of the filament to the hot glue gun again,  locking it in place. Repeat this for all part 1s. once done attach the part 2s on the end in the same way.

2. Now tie a small knot in the end of the string, using the unbent paper clip push it through the holes like shown. Push the same knot          through the hole in the expandable part, tying it on, and sniping the excess.

3. Follow the instructions in step one to attach the expandable piece to the remaining hole in the bottom hemisphere of the egg.

4. With this done, now tie a knot in the top of the string and use the paper clip to push it through. Now, play with the length of the sting,  holding the string to the outside of the egg to find a length that will let it close while giving it the max extending distance. When you have  found this this length drip 3 drops of super glue in the hole and let it dry, being careful not to let the glue drip on to the moving parts.

5. Attach the spider to the top of the expandable piece using the method described in step one, if you want you can bend the legs down. If  the egg is having a hard time staying shut, you can put a small piece of clear tape over the front.
