Picture of Pocket Merry-Go-Round
This nice little toy can keep a little kid like my brother happy for hours. It's customizable, fun, and easy.

*This was entered into the pocket-sized contest, Mad Science Fair, and Make ti Glow Contest (you'll see why in step 4). Please vote if you liked it... thanks!

P.S. I will just show you what I did. Due to the flexibility of this, you can do anything your imagination desires.

Step 1: Materials

This is very flexible. You can pretty much use any type of everything

Needed:
-casing (from aluminum foil to a small cardboard box to pvc pipe to...whatever you want, basically)
-battery (battery should be almost dead to prevent the motor from going too fast.)
-motor (any size, power)
-any circular object with a hole in the center (for the motor to go in) ( I used the bottom of a soda can with edges bent in)
-action figures, small objects, etc.
-tape
-hot glue (recommended)

Step 2: Join Motor and Battery

Insert the battery and motor into either end of the casing. One of the wires from the motor will go to the side of the battery inside the casing., and the other will go to the other side.

Hot glue or tape the wire to the side of the battery inside the casing, and lead the other wire outside.

Step 3: Attach Base of Merry-Go-Round to the Motor

What the title says.

Step 4: Add Figures to the Merry-Go-Round

I couldn't find any spare action figures, so I settled with this plastic food.

Anyways, hot-glue or tape the things you used onto the base.

You can also add LEDs to the base and use a not dead battery, and see circles of light

Step 5: To Use:

Touch the wire that is extending to the end of the battery that's sticking out.

Step 6: Modifications

Picture of Modifications
If it goes to fast, you can:
A- use a weaker battery
B-add a resistor
C- use heavier weights for the figures
D-Add flaps or something of that sort on the bottom to add drag to the spinning
E- use a weaker motor

You may want to consider not giving the cut up end of a pop can to a child. They tend to stick everything in their mouths, and impromptu oral surgery is not a fun way to spend an evening. Trust me.

My little brothers are old enough not to put that in their mouths but if you're making it for even younger kids, you should use something safer of course
