how do you make a hovercraft move?

Yep.  A fan will do the trick, or if it's a vehicle used for a specific purpose (like carrying something from set point A to set point B) a pulley system would work.  I don't know the exact equations involved, but the fan's windpower strength should be (obviously) greater than the mass of the vehicle, and should have some kind of failsafe cutoff switch as well as a means to decrease power to the fan, for (again, obviously) safety reasons.

You can make a ball bearing launcher:\nhttp://my.execpc.com/~rhoadley/maglnch.htm\n\nYou can make your own levitating MagLev train:\nhttp://my.execpc.com/~rhoadley/magtrain.htm\n\nOther info is available here:\nhttp://www.kn.sbc.com/wired/fil/pages/listmagnetsan1.html

Just drag it upwards.

It is simple, open a old mouse and see, there are two wheels,  one is for horizontal movements and the another one is for vertical movements. when you move the mouse up&dowm the vertical mouse whell will rotate, while rotateing there is a LED and sensor will contact eachother, then the mouse pointer will move up and down. same for horizontal movement.....

a bowl of water, a cork magnet tape and a sewing needle.\n\nFill the bowl with water. Take the needle and rub it on the magnet back and fouth for a long period of time 15 min will about do it. After you are down take the sewing needle and take it to the top of the cork. Take the cork and needle combo and place the cork bottom side in the water. \n\nIf you move the bowl the needle will move.

You run the fishing line through the straws.  Tape the straws together loosely with the duct tape.\n\nYou can then control finger movement by tugging on the lines.

just click and drag the folders/items around in the menu...\n\n\n\nJust click on it, and don't release the mouse button.  you should see a little black line.  Release the mouse button when the item is where you want it to be.\n\nit takes a little practice :)

a. Calculate the horizontal component of the 485 N.\nFh = 485 N*cos35\nCalculate the force of friction.\nFf = 0.57*319 N\nCalculate the net force.\nFn = Fh-Ff\nCalculate the mass of the box.\nW = m*g\nCalculate the acceleration.\nFn = m*a\nCalculate time to move s = 4.00 meters\ns = (1/2)*a*t^2\n\nb. Repeat with uk = 0.75

Yes all u hav 2 do is Drag it like the old verison real simple. just use ur mouse  arrow then just drag it where u want it make sure that u only see the white arrow and then make sure u keep hold off the button and make that u didn't click a icon cause then u'll just drag that icon. \n\n*It might not work the very first time but just keep trying*

make a mini lava-lamp-like thingy.  get a cup, fill it about 3/4 full.  add food coloring, if u want.  pour a layer of oil about a centimeter thick.  then, pour salt, sugar, or sand, or all three on top of the oil.  it'll go up and down for a while, then the solid will settle at the bottom and the oil float stay on top.

Use a mouse pad, make sure its on a level surface.

I suggest you build an anti-gravity lifter device that is able to float in the air without anything supporting it.\n\nhttp://www.amazing1.com/grav.htm

It looked like the hover boards worked with some sort of magnet on the bottom that probably conteracted with the earth's magnetic force. Since, water isn't magnetic, the hoverboard wouldn't work on water. Thats what I thought at least.

Sroll sreen up or down with wheel on your mouse

get like a lever, those moving stuff that you can place stuff on then just roll it. Or get more than 1 person

Try using an airplane, a navigational wheel, or something along those lines.
