With Pi Day (March 14) coming up, my husband and I decided to just go crazy with it. We’ll blog about the festivities later, but for now… I want to blog about the piece de resistance.. our PInata! Neither of us had ever been involved with making a pinata before, and it sounded like a fun – and wholly appropriate – challenge!
This would be a fun project for any couple or family to do together. Or, hey, any pi-obsessed individual… but I will say that two sets of hands REALLY helped it go faster, and there were many times where the extra set of hands helped with handling.
Of course, the principles of design that we utilized in the creation of our PInata could be applied to many different themes and shapes of pinatas, so go nuts with it. If it’s not in the cards for you to make one for this year’s Pi day, consider other occasions that would/could call for a Pinata.
Traditionally, it seems that you’re supposed to paper mache a balloon, and use that as your base. We couldn’t think of any possible way that would fit with our ideas, so we had to Macguyver a solution. Here is what we came up with. (Warning, this will be a fairly photo-heavy blog entry!)
You Will Need:
Large piece of bristol board or cardboard, or multiple pieces taped together
Ribbon, string, whatever
Stuff to fill it with
My husband had a large slab of 2″ thick styrofoam in his workshop. He cut two 2′ x 2′ squares, and glued them together to make one 4″ thick square. I drew an outline of a Pi symbol, being sure to not only keep the whole thing proportionate, but also make the leg sections wide enough to “hold a lot of stuff”.
He then used both a table saw (to cut the rough shape) and a hand saw (to trim it close to the shape) to cut the shape out of the styro block, then fine tuned the edges with a sanding block.
I then covered the entire thing with plastic wrap, loosely. This was to make it easier to remove our pinata from the mould later on.
A little “do as I say, not as I do”, here: Before you start paper macheing (is that a word?), you should trace your styro shape out onto bristol board or cardboard. We didn’t, and had to deal with some hassle as a result – more on that later.
Then, we made our paper machee “glue” from about 2 parts flour to 3 parts water for our glue, then added a couple tsp of cinnamon because I hate the smell of flour water. It really helped! We cut out newspapers into 1-2″ strips, and laid out some garbage bags as a drop cloth.
For our initial round of paper machee, we did a total of about 2 layers over 1 face and the whole way around our styrofoam shape, then let it dry completely.
We got impatient with it at this point and removed the shell from the styrofoam before adding another 2 layers of paper mache, but in hindsight.. I wouldn’t suggest doing that. Just add another couple layers over the ones you already did, and let it dry completely again.
Flip it over and carefully extract the styrofoam. You may or may not need to let the inside dry some more. Or extract a kitten from it, as we found ourselves doing repeatedly!
Concurrently to all this, you should also be doing a total of 4 or so layers of paper mache to the shape you traced on the cardboard. (We didn’t! We traced our final, extracted shell onto newspaper and layered THAT.. but then it shrank and we had to Macguyver it some more!). This will be the piece that seals off the other face of your pinata.
Another thing we didn’t do was reinforce the holes that would hang the pinata. I’d suggest doing that by figuring out approximately where you are going to cut the holes in the top, and run a bunch of duct tape across it, either from the inside of the top, the outside of the top, or both, then cut your holes. Also, now is a good time to run a length of ribbon or string through those holes and tie off on the outside – it will help you run your string, rope, or whatever through the holes later, as doing so to a finished pinata would be really difficult.
While all of that is drying, you’re probably looking forward to stuffing it and getting this show on the road. We took the time to go to the local Dollar Tree, which was an excellent source of all KINDS of weird stuff to pack into our PInata!
I wasn’t much into the idea of using poufs of tissue paper to space out goodies, so I bought a pack of leis instead – double duty stuffing! In addition to that, we included a kite (because it seemed hilarious to put a kite in a PInata!), candy, etc etc.
Also, we cut 3 or 4 rough 4″ blocks from the scraps of foam that we had cut away from the main Pi shape earlier on, to use as structural support pillars inside the pinata.
When everything is dry, position your foam pillars inside your pinata cavity, then evenly stuff it with your.. stuff. Place the flat Pi shape on top, and weigh it down with something – we used cans of salmon and roasted red peppers, lol. Go ahead and paper mache your way around that whole edge a couple of times, and let that sucker dry completely.
At this point, we were so excited to see the finished product that we forgot to continue taking photos, so I’ll have to just describe how we went about decorating our pinata.
First of all, as it was a combined Pi & St Patty’s Day party, we decided that it should be bright green, and be wearing a black belt with a yellow buckle. We cut up a ton of tissue paper into roughly 2″ wide strips, and then into 2″ x 2″ squares. Then, we drew the lines for the belt and buckle
Using a wide paintbrush and some regular white Elmer’s Glue, we painted the entire back and sides of the pinata with glue, and covered it with a layer of tissue squares. Green squares over most of it, black squares within the lines of the belt. This helped prevent any show-through of the paper mache between the poufs.
IF we were truly smart, we would have either left it like this, or at least done the traditional fringe thing.. but NO. We decided to get fancy, and harken back to our kindergarten days with some .. I have no idea what you call it. Tissue paper pouf. Basically, we took a square of tissue paper, centered it around the end of a pencil, dipped it in glue, and stuck it to the PInata. Repeat with another pouf pretty close to it.. ad nauseum.
Once you’ve got the back and sides covered and they’ve dried, flip it over and repeat with the front, starting with completely covering it with a layer of squares.
NB: We soon gave up on the pencil and just poked out fingers into roughly the center, and then dipped the resulting peak in the glue. While that helped it go faster, it was still a serious undertaking. The back side and sides took a couple evenings, and then the front took another evening..but in the end, it was totally worth it.
Run your rope/string/whatever through the holes, using the earlier ribbon to pull it through, hang it up, and beat the crap out of it. OR, be like us, and refuse to take part in the destruction of your labor of love, and just videotape your friends looking like goofballs 🙂
As a closing note, put more thought into what kinds of things will survive the bashing than we did. For the record, pixy stix may result in sugar everywhere. Toys and kazoos may break. Small and compact is best!
