Introduction: Knex Comet

Picture of Knex Comet

--This is a post by my 11 year old brother--

A "really cool comet" made of Knex that you can throw like a foot ball outside, or even a Knex flower by taking the rubber band of the tail (if the imagination allows).

24 Tiny connectors
8 Flexible connectors
16 Green 135º pieces
2 White 360º pieces
1 Rubber band

Step 1: First Step

Picture of First Step

Take the white circular piece and attach the eight (8) short connectors to it. On those, attach the eight (8) 135º green pieces.

--and repeat

Now, on ONE of the halves, attach the eight (8) short connectors (as shown in the first two pictures), and then put the two halves together (shown in third picture).

Step 2: Adding the Bottom (or Top)

Picture of Adding the Bottom (or Top)

Attach to each of the eight (8) green pieces, a longer (as long as desired) flexible connector. We chose the green glow in the dark ones.

Step 3: Now, Wrap It Up (pun Intended)

Just rubber band the ends and twist, and viola.

Comets are small Solar System bodies that orbit the Sun and, when close enough to the Sun, exhibit a visible coma (or atmosphere) and/or a tail — both primarily from the effects of solar radiation upon the comet's nucleus. Comet nuclei are themselves loose collections of ice, dust and small rocky particles, measuring a few kilometres or tens of kilometres across. Comets have a variety of different orbital periods, ranging from a few years, to hundreds of thousands of years, while some are believed to pass through the inner Solar System only once before being thrown out into interstellar space. Short-period comets are thought to originate in the Kuiper Belt, or associated scattered disc,[1] which lie beyond the orbit of Neptune. Long-period comets are believed to originate at a very much greater distance from the Sun, in a cloud (the Oort cloud) consisting of debris left over from the condensation of the solar nebula. Comets are thrown from these outer reaches of the Solar System inwards towards the Sun by gravitational perturbations from the outer planets (in the case of Kuiper Belt objects) or nearby stars (in the case of Oort Cloud objects), or as a result of collisions. Comets leave a trail of debris behind them. If the comet's path crosses Earth's path, then at that point may be meteor showers as the Earth passes through the trail of debris. The Perseid meteor shower occurs every year between August 9 and 13 when the Earth passes through the orbit of the comet Swift-Tuttle. Halley's comet is the source of the Orionid shower in October. Comets are distinguished from asteroids by the presence of a coma and/or tail, though very old comets that have lost all their volatile materials may come to resemble asteroids.[2] Asteroids are also believed to have a different origin from comets, having formed in the inner Solar System rather than the outer Solar System.[3] Recent findings have, however, somewhat blurred the distinction between asteroids and comets;[4] see also Asteroid: Terminology. There are a reported 3,354 known comets as of November 2007,[5] of which several hundred are short-period. This number is steadily increasing. However, this represents only a tiny fraction of the total potential comet population: the reservoir of comet-like bodies in the outer solar system may number one trillion.[6] The number of naked-eye comets averages to roughly one per year,[7] though many of these are faint and unspectacular. When a historically bright or notable naked-eye comet is witnessed by many people, it is often considered a Great comet. The word "comet" came to the English language through Latin cometes from the Greek word komē, meaning "hair of the head"; Aristotle first used the derivation komētēs to depict comets as "stars with hair." The astronomical symbol for comets (☄) accordingly consists of a disc with a hairlike tail. -wikipedia

lol thats funny, cause i dont think this is a rock floating in space

flames10391 (author)apples!!!!!2008-06-20

well timbruyns asked, so i gave him assistance lol

apples!!!!! (author)flames103912008-06-20

lol, but i think he knows what a comet in space is, but didnt think that this thing was meant to be the same thing.

I_am_Canadian (author)2008-06-22

You dont know what a comet is? uh oh....

hellpilot (author)I_am_Canadian2008-06-23

I know I am being picky but this was flagged as incomplete. +Your only instructions were to follow the pictures. +The last step does not get you all the way to the final project.

Vynash (author)reedz2008-06-18

ummm excuse me he has good instructions

reedz (author)Vynash2008-06-18

*sighs* He has changed it a little bit so far, such as added a last step since I commented. I'm sorry for caring enough to want him to improve.

Vynash (author)reedz2008-06-18

oh OK thanks for explaining it

reedz (author)reedz2008-06-17

Sorry for being like that, but there is pretty much no standard on here anymore.

s0lekill3r (author)reedz2008-06-17

Yeah, people think that by posting a couple pictures and saying to follow them that we can actually make these things.

reedz (author)s0lekill3r2008-06-17

Well... you could... it just doesn't look very good as an instructable, maybe a slide-show

I_am_Canadian (author)reedz2008-06-18

Its good enugh for most people to use.

s0lekill3r (author)I_am_Canadian2008-06-18

Yeah, but that's not the point. People are constantly posting incomplete instructions and think that it's ok.

anor09 (author)s0lekill3r2008-06-18

I'm going to go through and fix it for him...sorry about not proof-reading before i let him publish

I_am_Canadian (author)anor092008-06-18

I think its fine.

apples!!!!! (author)reedz2008-06-17

i get what you mean, but at least it's simple enough to follow
