In this instructable I will show you how to make a 1up mushroom out of
4 ping pong balls
alot of reynolds wrap
a used wrap of duct tape
and of course ALOT duct tape.

I think one could make this in 20 minutes. It took me much longer because i had a dozen different ideas and only one would work. I made a blue mushroom, which really isn't a 1up, because it's my favorite color. If you want a true one up use green duct tape. If you want a power Shroom use red. The other colors you will need are black (for the eyes) and white (for the spots and stem). When you start make sure you have alot of your white, and your green (or other color if you use a different color)

Step 1: Umbrella

first your gonna want to wrap your ping pong balls in aluminum foil. Make sure you give it a good wrapping. Then start wrapping it with tape. Remember you want the final shape to be a circle when viewed from above. So try to duct tape it that shape. When your satisfied with the size your done.

Step 2: Stem

Here's when your empty roll of duct tape comes in handy. First your gonna want to cut one side all the way down. Then squeeze it till it's a 2 inch's in diameter. Then you will want to roll it in duct tape. You just made a stem.

note: image notes won't work for me right now so I'll put them here

Step 3: Details

Now to add the finishing touches. Now to add the stem and umbrella together simply duct tape them together. It helps to rip the duct tape down the middle. Then to add the eyes rip 2 strips of black tape and put it on the face. To add spots just rip of appropriate sized squares and stick on there at random. If the stem overlaps the umbrella, (like mine did) just tape the appropriate colors where they should be. (btw I didn't take pics of this after I did it, but your smart so you should figure it out).
