This year my nieces requested a Spongebob Squarepants pinata.  The challenge is to make the rectangular shape using paper maiche.  If you use cardboard as a base for the pinata, it may well be too difficult to break, especially amongst pre-kindergarten age kids.

Step 1: Flat sheet paper maiche

The trick is to make reasonably flat sheets of paper maiche from which to form Spongebob's body.  The overall dimensions I'm making are 12"X16"X4" for the body.  The top and bottom will be cardboard for stability and for connecting the sheets together; it won't prevent the main body from being broken.

First, I prep the support I will be using to build up the sheets.  I am using a piece of plywood, laminated with formica top, with a generous amount of vaseline smeared all over.  The vaseline will be key in getting the sheets off the top.

Prep the newspaper.  I like to cut in consistent size squares, about 2" for this project.
Thank you so much for your instruction this made me the best granny ever. Spongebob came out awesome. I made as big as my two year old grandson. 2-60 age group loved it. I used the gardening knee mat to 3D face in yellow. $1
Wow that was incredable! It almost broke my heart to see it broken open! What a lucky boy. Thanks for sharing.
WOW WOW WOW, I have made my son't piñatas every year but this one because he wanted sponge bob, and I had NO idea how to do it so it would look good.
Nice project, Looks like I have a to do list. Can you tell us what sealer you used for the face? (unless I missed it)
I used a 'foam safe' 2 part epoxy, the kind used for fiberglass or carbon fiber. But not the auto store type resin, that will melt the glue. You might also use 5 min epoxy, or possibly even something like wood glue. As well, I think you would paint it directly with acrylic paint (not too watered down).
Nice use of foam! :D I wish I wish I wish there was a picture of him busting open.
i know what IM going to be making!!!!!!!
Why hasn't this been featured yet?<br> <br> Nice work my man!<br>
Nothing better than performance art. Build to destroy. That's what we said in the Army too. Good times.
