A cheap, concealable toy for a mischievous kid.
  1. Find a rubber band and some paper.
  2. Tear out a small square of paper, about the size of a regular post-it note. This is even easier if you just start with a post-it note.
  3. Fold the paper in half, and then roll it along it's short axis, and flatten. This should create a small roll of paper about 4 cm. long, .75 cm. wide, and .35 cm. thick.
  4. Fold this roll in half, and squeeze it shut. You should now have a hard, dangerous-looking piece of paper ammunition.
  5. Place the rubber band around the tips of the index finger and thumb of your dominant hand, your palm facing outward.
  6. Grasp the far side of the rubber band with the index finger and thumb of your other hand, and pull it back as far as you can while still maintaining a 7 cm. gap in your first hand. This is the firing position.
  7. Now hook the paper wasp over the far side of the rubber band (NOT both sides!) and pull it back to the firing position. Make sure that it is perfectly centered on the band.
  8. Take aim and fire as you would a slingshot. ZING!

This device takes some practice to be able to make well and fire accurately. You can make a lot of ammunition all at once (when bored in class, perhaps) and carry it in your pocket. Target practice in your room while avoiding doing your homework is suggested.

Experiment with the size and thickness of your wasps. The size described above is the "standard" size, but many different models will work. One interesting variation is an extremely small, very well-rolled wasp, which flies fast and hurts a lot on impact. Remember though,it does have to be long enough to loop over the rubber band.

Finding a good rubber band is the key. It should be as long as possible, while still maintaining the ability to hold it slightly stretched between your index finger and thumb, so it won't bunch up while firing. It should obviously be as elastic as possible. The cross section of the band should also be as small as possible and still not break when you fire. You will develop a "feel" for a good rubber band.

You can also use paper clips, cut in half, as ammunition. WARNING! This is very dangerous! Use them only for target practice against inanimate objects you don't care about. I have fired them through empty soda cans and full juice boxes. They can embed themselves in wood if the prongs happen to be pointing forward when they hit. This means they can also embed themselves in someone's leg, causing certain death! They fly extremely fast (because of their low air resistance) and tend to ricochet unpredictably.

Paper wasps are insects belonging to the Order Hymenoptera. They are related to other wasps, bees, ants, and sawflies. There are 22 species of paper wasp in North America and about 700 species worldwide. Members of the group are active during daylight hours. They return to the nest for night and are inactive until the return of light. Paper wasps are more active as the temperature rises, being lethargic on cool days to very active on hot summer days.

The nest of paper wasps is usually suspended upside down from a sturdy stem, making the nest resemble an inverted umbrella, which earns them the alternate name of umbrella wasps. This tough stem is then treated with an ant repellant secretion which aids in avoiding predation by and egg/larvae loss to ants. The nest is composed of a single tier of hexagonal shaped cells. An egg is laid by the queen in each cell, which remain open for the feeding of the young until the larvae pupate, sealing the cell. They then emerge as young adult wasps.

Appearance
Paper wasps may be from 3/4 to 1 " in length. The size and coloration vary among the different species. They are characterized by two pair of dark wings which are folded along their body when not in use. Some color variants are striped, red, brown, and black paper wasps. Paper wasps also possess small heads, narrow waists, and long hind legs which trail them in flight.

Social structure
Their name is derived from their practice of chewing plant fibers and wood, mixing the pulp with saliva, then constructing their nest from the resultant paperlike material. Paper wasps are semi-social insects. Their society is divided into 3 castes comprised of males, workers, and queens.

Queen
Mated queens overwinter in protected crevices, stumps, burrows, or attics. They emerge in spring to build a small nest in which they lay eggs. The young queen hunts for the small brood, defends her nest, and continues with nest expansion.

Workers
This small first generation are smaller sterile worker females. Their job is to care for the larvae and defend the nest. Paper wasps hunt other insects for the feeding of the legless, grub-like brood, partially chewing the flesh to present to the young. Prey species include caterpillars, flies, and beetle larvae. The sterile workers also join the queen in nest expansion. The nest may have as few as 10 to over 100 workers in attendance.

Males
Later in the season males are hatched along with young non-sterile females. The sole purpose of the male paper wasp is to impregnate the young queens-to-be. Males do not possess a sting, as the sting is a modification of the ovipositor, a distinctively female feature.

Beneficial insects
Paper wasps are usually considered a beneficial species as they harvest large numbers of crop harming insects to feed their brood. This biological means of pest control helps humans in their efforts to control unwanted pest species. Unless the nest is in an area shared by humans it is suggested leaving them unmolested, letting the natural cycle remove them with the coming of winter. Nests are not reused the following year by emerging queens, who start each cycle from scratch.

Adults feed on nectar as well as insects.

Upon breeding, the future queens take cover in their protective winter hideaway, to emerge the following spring and start the cycle for another year. All members of the colony die at the onset of cold weather, with the exception of the impregnated young queens.

Nest protection is a major concern and the wasps will attack maurauders. Wasps are not as aggressive as yellow jackets or hornets in nest defense, usually only attacking when invaders get within close proximity of the nest.

Stings
The majority of paper wasp stings are a result of nest defense. Other stings can occur due to chance encounters where the wasp's space is invaded in the field. Stings can occur when a wasp simply lights upon an unwary person who then moves in a way the wasp interprets as threatening. Stings are painful and the wasps can deliver multiple stings, unlike true bees. The sting delivers venon which creates a burning/itching sensation as well as swelling of the site. Multiple stings can produce an allergic reaction (anaphylaxis) in sensitive individuals who should seek immediate medical care if stung. Kits are available for field treatment of stings. Application of meat tenderizer helps to deactivate the toxin of the sting.
