How do you make a miniature float?

put the miniature in a boat (hehe)

This is potentially a massive and complex task.\nSearch the web for "computational fluid dynamics".  Here's what I found in a couple of minutes:\nThe 1st ref. below has some interesting simulation ideas (but unfortunately for a liquid, not air).\nThe next discusses things you should know before even deciding whether to do this.\nThe last gives links to software downloads.

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.

The site below has animated objects. I hope this helps!

JUST MAKE A 3D-MODEL OF A PRISM OUT OF A CARDBOARD OR THERMACOL

well,first of all you can take a hollow cylinder.then on one end of the cylinder,attach a rubber sheet(thin one).then you can attach a stick with flat head  fixed to it to the rubber sheet.the flat head will prevent the balloon from bursting in the cylinder.now to make it work,first pull the stick towards you,like a catapult,and then release it.the rubber attachment will make it go ahead and strike the water baloon.i tried it.it worked.\nif you face any problem,contact me.

make anything out of the following\nperiscope\nvolcano (Although I don't suggest this - it is a very old project and maybe many will turn up using this)\nA mini hovercraft or hot air baloon (info can be found on net)\nI don't know what it is called but if you know that thing in which we have to take a small hoop across a wire (which is not straight) without touching it. If touched, it will make a sound.\n\nIf none of this suits you, you might watch Backyard Science at National Geographic Channel

for a model of a ship from the 1400 you can look into any kind of painting from that period showing ships.for building a float-able model you can use polystyrene(the white light stuff used to protect a new TV in her box for example)you take a cube of this and with a sharp cutter carve the form of the ship out of it.then some paint and imagination will do the rest.oh,in order to make it float straight you must make it as symmetrical as possible and add some weight on the lower part.a long nail or screw will do f.e.

If it's just a school project, you might try pumping it or simply use a bucket. It depends on how large your model and pocket are.\nIn actual aqueducts, the water is already at a higher level (like a mountain spring or lake) so I think it would be fair to replicate that situation.

one option is to freeze the water, shape it into a concave lens shape, polish it till its transparent, and use the disk like a magnifying glass on the match head.\n\ni saw this actually done on myth busters, although it didn't go very well

Cut the top off of a milk carton. Glue a popsicle stick to the side of the plastic that reaches well above the carton, glue another stick perpendicular to the first to make an L shape. Add a fabric or other material sail. It will float!

You have to start with the Jolly Roger - scull and cross bones.  Sails could be screwers and light cardboard curved with centre holes top and bottom, nicely decorated, two triangular ones at the front.  The hull could be a Plastic coke bottle cut lengthways.  Glue something heavy to the bottom and then a layer of foam for the screwers to stick into.  Fashion  cardboard to fit as a deck, make holes for the screwers.  Find some netting (stocking material or the stuff they use in fruit punnets.  Brown wool for rigging and put it all together and then caste off me hearties.

Make one yourself.  Use MS Paint or if you're really feeling fancy, Photoshop.  Of course, then you'll have to host it somewhere...

Easy!\nStir the mixture into water. Sand sinks. Styrofoam floats.\nScoop the Styrofoam off the water surface with a strainer.\nPour off the water.

1. Get some wood, nails, screws, wood glue.\n2. Draw a scale design of the boat on a piece of paper.\n3. Cut up the........

1. you need firstly to have a total density equivalent to that of fresh or salt water(for whatever purposed required)\nthen bouyancy will be stable/maintained \nthis will make a suitable start\n2. forge a shape suitable to make the sub hydrodynamic, this will enable the prototype to glige through the water \n3. have fun!

Hi Manda\n\nTry putting them on a corkboard covered with green felt. Using some twist ties run threw the board. Then if you like you can put the m in a nice frame.\nJust an idea.\n\nLeon
