i plan to make a hang glider i want some real information about how i can make it and the real diminsions plz?

Sounds a bit dangerous!  But I;m sure if you google sometime like "hang gliding kits" then you should get somethin?!\n\nGood luck...and be careful!

Here is a great site that will take you through making paper airplanes from simple to complex. It will Just click on all the links (written in blue) for styles and directions: http://www.paperairplanes.co.uk/planes.php\n\nThese are just additional informative sites that will also cover the history of paper airplanes:\nhttp://paperplane.org/History/history.html\nhttp://www.exploratorium.edu/exploring/paper/airplanes.html

Well, 1st off, I suggest you buy one,(its alot less hassle). If you want to make one you would need "marine" plywood", "fiber-glass resin and Cloth", Paint, Small "skegs" and a "design-shape" to cut your board with. It is not an easy task. Alot of sanding.layering "glass". BUY a board don't try makin one!!!!!.....good luck!

Wow, thats a tuff one. Have you considered cardboard or wire and fabric? How much time do you have because this seems like a time consuming task. You could look on the internet fo ideas that might help you out. It depends on what you want it to look like.

Draw a chair with legs, but make the entire chair weird. Since nobody has to sit on it you can make it disproportionate.\nYou could add wings, fairy dust and even a cloud that the chair is sitting on. Of you should make the chair more of a 'stool' like a toadstool ( magic mushroom chair), just add a back to it.

Get it peirced and hang 20kg weights on it, that will stretch it to as long as you want.

Rather than detail such info here, I have gathered several websites to help you on your way. \n \nAs for doing it inexpensively, you can only cut so many expenses, but as you educate yourself on thier general construction and avaialble parts resources; you should be able to id where dollars can be cut back.\n\nIt looks like some wings are available for only $62.00, my estimate for an all told price would be around 200-300.  YOu would need to define your idea of inexpensive to id a possible model for your goal.\n\nI wish you success and fun in your endeavor.  \n\nP.S.  Thanks for mentioning the ZAGI...now I am interested too, they sound like a lot of fun.

Make them aerodynamic and make sure the materials used are as light as possible.  The cone should be as centered as possible and the air fins should be straight and placed evenly so it will fly straight, if it wobbles it will create drag and limit it's height. Also if you give the cone some drag when it's falling back to earth, you can impliment a cool parachute as well!

3/4" Marine plywood: (shaped to taste hehehe!) add a little rocker....cover with marine epoxy...sand till smooth... paint.. whalla!!\nthen shuvit shuvit shuvit!!!!\n\n- good for flat water skimboarding! hikhikhik!!

first, you would need to know the final velocity of the glider (velocity right when it touches the spring), secondly, you would need to know the spring constant, k.  obviously, the greater the spring constant, the shorter the time of contact would be.  you would then have to go through various steps:\n\nin a nuttshell:\n1)  find the force/momentum of the glider when it hits\n2)  from the info in #1, you will be able to find the length of the springs compression, as well as the time it takes for it to bring the glider to rest.\n3)  then using the spring constant, you'd need to find out how long it'd take for the spring to push a glider (remember, the glider is at rest, ie. v-knot=0) of 900g from its compressed state (found in step 2).\n4)  adding the times found in steps 2 and 3 should give you your final answer.

Is this a real-world or mathematically-defined object?  Three dimensional?  Not enough info.\nIf a real object: You can do all sorts of hanging and balancing, but 3D objects, and especially those that are not clean geometric shapes (picture a randomly shaped rock) can be tough, requiring the assignment of a coordinate system, attachment of balancing pivot points, etc.  2D real objects are a snap: Hang from any point, draw a vertical line through the point, repeat at another point; where the lines intersect is the CM.  Here's a neat trick I read somewhere for finding the CM of something long & skinny like a stick:  Hold it horizontal, resting on two small sticks that are far enough apart so the CM is in between.  Slowly move the sticks together; they will meet at the CM!  I think you can do this with a flat 2D piece and three pins if you happen to have three hands.

Because of the weight of the sticks, you will probably need to split them into 1/4 or 1/8 widths, wet them and curve then for the wing shape (rounded on top), and then glue them in a framework. Use tissue paper. If you make a propeller, you could power it with a wound rubber band.\n\nConstructions such as this were made by aeronautic teenagers 50 years ago, but they usually used balsa wood.

Just pulling something from the top of my head, and thinking about the new releases....Do "King Kong", although I haven't seen the new movie yet, I am sure its pretty close to the original.  Build skyscrapers out of cardboard boxes, paint them up to look like buildings.  Go out and get a gorilla stuffed animal, a dinosaur stuffed animal, some small toy cars, maybe make a highway out of cardboard too.  Not sure how big your campsite is, but this would be an easy way to decorate.  Good Luck, and have fun!

Here's a site with alot of different ideas and difficulty levels with instructions.  Maybe you can find something here.\n\nOr you can tell us more about what you are wanting to do and what you like and we might be more helpful on here.\n\nhttp://www.all-science-fair-projects.com/

Lots of cool ways to make a parrot...\n\nyou could go the paper mache route..take a long balloon, some strips of news paper, elmers glue and water. (disposable clothes and containers) wood glue works reaaaaaaally well!\n\nmix half and half of the glue and water....(it should be a thick gooey liquidy consistency...not toothpaste but not milk either..)dip the strips in and cover the balloon with them in a criss-cross pattern...let dry..repeat a few times.\n\ntake a toilet paper roll and  cut and glue it into a beak shape..duct tape it onto a small balloon..repeat the paper mache process...\n\nwhen they are both dry..paint them...glue them together Or paper mache them together...add some craft feathers for the tail and head. pipe cleaners for legs. \n\nyou could make a toucan by collage-ing fruit loops boxes. \n\nyou could take a babies one piece outfit with hood..(like a snow suit bought at a goodwill store) and stuff it with news paper and glue feathers all over it...add a \n ball of some sort for the face and a beak. \n\nor...make a rag doll parrot..take some old clothes/tee shirts of different colors and rip them up! sew a crude parrot shape and stuff it with the rags. then take some of the rippings and tie them on to make colorful feathers. \n\npoint out that all of these processes require recycling which is good for the environment...\n\nhave fun!

You don't say how far the egg will drop.\n\nI would make a cradle for the egg out of straws, about half a dozen taped together at the ends, the egg just held in the center by friction.\n\nThen I would construct a "cage" about one straw long on each of its sides (six sides for a cube) Use glue to attach straws together and only leave about an inch between straws. Leave one side open until you put the cradle with the egg inside, attached to the center of two sides of the cage. then finish the last side. Glue diagonal half-straws across each corner (three for each corner). That would be my best off the top of the head solution.  A second cage could be built around the first. You didn't mention any size restrictions. The bigger the structure is, compared to its weight, the more wind resistance it will have, and the slower it will fall.  The idea is to let the cage absorb the force of the impact but insulate the egg from it as much as you can.\n\nGood luck.
