If you’ve been on Pinterest for any longer than an hour, you’ve probably seen this image. I would like to first say, you have no idea how annoying it was to try to find the original post for this idea. Even now, I can’t even be 100% this is even it, but let it be known, I tried.
I discovered a stash of balloons the other day and I decided to give this a try. Without the help of the kids, because I just don’t have that kind of patience nor am I quite that insane.
The balloons I had were “standard” size but I discovered that this means smaller than expected marbles. Cheap balloons are meant to hold air, not necessarily dense, heavy water. I’m warning you now.
I filled up the first balloon with water at the kitchen sink at our drinking water tap faucet because I figured the higher pressure would make quick work of it. The balloon’s opening did not fit tightly over the spout, it filled the balloon but wasn’t enough to expand it. The water simply overflowed back out. Since the kitchen faucet had a sprayer head, it wouldn’t fit over that so I moved into the bathroom, which had the only spout in the house that the balloon’s end would fit snugly on.
So now I’m in the bathroom with my balloons and food coloring. I used the cheap liquid drops – the kind that comes in the bottles that look like garden gnomes. You know the kind I’m talking about.
I put a couple drops of the coloring in an empty balloon and then fit the end over the tap and gently turned the water on. It expanded as I had hoped, but I didn’t try to fill it very full for fear of it exploding. I didn’t want to reuse that balloon, either, so when I turned it over to empty it, the water violently erupted and red water went everywhere! It was a mess.
After I cleaned that up, I took a new balloon, added a couple drops of the coloring and tried again. It got about the size of a very large grapefruit when I carefully removed it from the faucet and tied off the end. It is crucial to NOT fumble-finger this part unless you are outside and you don’t care about the mess. I ended up with four filled balloons, which I gingerly placed in a bucket (again, because I kept imagining one would burst) and then set it outside overnight.
Sparring Partner said that they would end up sticking together when the latex froze, however they did not, and really? It wouldn’t have mattered if they had. This morning, I cut the balloons away and I was left with my ice marbles.
They are not perfectly round, so don’t expect them to be if you try this. The food coloring actually settles while the water is freezing, which resulted in a more ombre affect. Don’t put the final product anywhere you don’t want stained when it melts, like your deck rail or porch or steps. Of course, I don’t care, so I did sit mine on top of the deck.
OH! And I almost forgot: there’s no need to wait until the outside temps reach and maintain freezing. Since the balloons don’t get THAT big, you could just put them in a bowl or container and put that in the freezer, especially if you have a chest or storage freezer. I would recommend you put them inside something, just in case the balloon gives way.
