50 Dangerous Things (You Should Let Your Children Do): Explode a Bottle in the Freezer

50 Dangerous Things: Explode a Glass Bottle

Task:

Fill and freeze a glass bottle, and see the natural power of ice in action.

Requires:

  • Sealable glass bottle
  • Plastic container (to hold the bottle bits post-explosion)

Possible Hazards:

  • Cuts and scrapes
  • Mess

How It All Went Down:

I can think of multiple times we accidentally exploded a bottle in the freezer as kids, but flipping through the 50 Dangerous Things book, I realized my kids have never experienced this. If you’re looking for somewhere small to start on your own 50 Dangerous Things journey, this is a good one. You probably already have everything you need, and it’s easy to do while you’re home and doing other things. Bonus: kids get really excited about breaking things, especially something as forbidden as glass.

The author suggests using a resealable soda bottle, but all of our glass soda and beer bottles had bottle caps, not screw tops. Empty glass vinegar, wine, or liquor bottles will all work. Just remember – the bigger your bottle, the longer it will take to freeze … and the bigger the mess!

Fill the glass bottle with water, and screw on the cap. Using a Sharpie, draw on the bottle where you think it will break. Place the bottle in a plastic container. This is a must, unless you want to spend an entire day picking broken glass out of your freezer. You can also cover the plastic container with a cloth to keep any stray glass shards from flying around your freezer.

Freeze a glass bottle

Now wait for your bottle to freeze. A standard home freezer will take at least an hour to freeze a small glass bottle. We used our deep freezer, which is colder and freezes faster. After an hour has passed, check the bottle by gently rocking the plastic container to see if the contents are frozen. Check back every 30 minutes or so to see if your bottle has broken.

Once the bottle has exploded (bonus points if you hear it!), carefully remove the plastic container and the broken bottle from the freezer. Observe your bottle and hypothesize about why it broke in the spots it did. You can repeat the experiment with different shapes and sizes of bottles, and compare how long they take to freeze and how differently they explode.

It’s kind of amazing how something as innocuous as freezing water can cause so much damage. How do you topple a mountain? Expose it to season after season of freezing water, which expands as it freezes and forms large cracks.

Exploded glass bottle

We joke about how most of the tasks we’ve completed in the 50 Dangerous Things book really aren’t dangerous at all, but this task gets the honors of producing our first real injury. I warned Eli over and over again that broken glass can be ridiculously sharp. Sure enough, he couldn’t resist and he sliced his finger open. I’ll warn you as well, but if your kids are anything like mine, it takes a teachable moment for the lesson (and the bandaid) to stick.

Life Skills Every Kid Should Know: How to Bake From a Box

In March I announced that we’d be starting a new series on The Risky Kids: Life Skills Every Kid Should Know. The response was wonderful – it turns out you agree that there are many things kids need to know beyond what they’re taught in school. You agreed with our suggestions for the series, and came up with many more life skills you’d like to see added to the list. You can find posts from the entire series on the Life Skills Every Kid Should Know page.

Rainbow cake

You know that in the past, I struggled with how to get my kids involved in the kitchen. You gave me some great ideas, which turned into inspiration for our Life Skills series. It was suggested that I let Elena pick out a box mix of a treat she likes. And so that’s what I ended up doing, in a roundabout sort of way.

She came to me one rainy afternoon asking if she could bake a rainbow cake. She’d seen one on Pinterest and followed the link to a very complicated recipe. The situation could’ve gone a few ways. I could’ve said yes, knowing ahead of time that one doesn’t just jump into a complicated layer cake recipe for their first solo baking experience without the likelihood that something along the 32 steps will go wrong. After all, isn’t failure a great teacher? I could’ve said no, let’s find something more manageable for a novice baker. Or I could say yes, but encourage an alternate plan to get the same result.

Had I said yes to the original recipe, and had she failed, we both would’ve ended up discouraged and mad. Me, for the waste of ingredients. Elena, for the realization that what looks easy on Pinterest isn’t always the case. In the future, I’d be wary of letting her try other recipes, and she might shy away from attempting any future baking projects for a long time. Had I said no, Elena would be less likely to ask again. And even if she did agree to something easier, it was a rainbow cake she wanted, not brownies or no-bake cookies.

Instead I said yes, but encouraged her to swap the actual cake recipe for a box mix. She was totally okay (and even relieved) with my suggestion. Box mixes, whether for cakes, brownies, bars or muffins, are the perfect intro to baking for every novice. They provide just enough practice for measuring to hone those skills. The directions are short and simple to follow, giving fledgling bakers experience reading recipes and making decisions. They’re also inexpensive, so if for whatever reason they don’t pan out (oh yes, I went there), you’re not quite as mad as you might be if you dropped $15 on ingredients. There’s such a huge variety of box mixes these days, for every taste and dietary restriction, that anyone can find something they’d want to bake.

Kids in the kitchen

On her first effort at baking from a box mix, I stayed in the kitchen – ready to help but keeping a respectful distance. She made the cake batter according to the directions on the box, and then customized  her white cake into a rainbow cake by following a tutorial on a baking blog. She made a bigger mess than I would make, she did things differently than I might do them, but the end result was the same: a delicious cake.

Now I realize you might balk at the idea of baking as a life skill you need to know. Plenty of people get by without ever turning on the oven. If you need something for the office pitch-in or you’re craving a brownie, you can just buy one, right? True, but like many “easy out” options in life, you miss something by not learning the hands-on way of doing the task. In attempting to bake, you’re paying attention to your food. You’re learning how to read a recipe and follow instructions. You learn how to use different tools in the kitchen.

There are other valuable lessons rolled up into baking from a box as well. Getting the kids involved in the shopping for the mix teaches budgeting and grocery shopping skills. How much does a box mix cost versus buying individual ingredients? Do they have all the ingredients they need, above and beyond what the box provides? What about equipment? Do they have the pans they’ll need? And then there’s the clean-up afterwards. Being proficient in the kitchen means cleaning up after yourself and leaving your workspace as you found it.

Maybe the kids try it, and realize baking just isn’t their thing. That’s okay! At least they can say they tried, and move on to other pursuits. I shared with Elena that I love baking from scratch, but cakes aren’t my forte. I started out with box mixes, spent a few years attempting to bake cakes from scratch and failing, and came back around to box mixes. It’s not failure – it’s realizing where your strengths are and where you should step back and find another way. Like the way to the local bakery when your kids’ birthdays roll around!

Apparently, baking rainbow cakes is Elena’s thing! The first one barely lasted through the day. Last week, she baked another, completely on her own. She entered this one in our neighborhood block party bake-off, and it took first place in the kids’ category. She was so proud of herself. Of course, I’m all about encouraging the kids to try new things, so I’m stocking up on a few kinds of brownie mixes next. I mean, they need to practice these valuable life skills that involve chocolate, right? I’m selfless like that!

Have you let your kids bake with box mixes yet? If so, what age did you start? And how about you? Did you start out on box mixes and graduate to baking from scratch?

In order to find these caches, you get the coordinates of the cache’s location and use a GPS to locate it. Once you find it, there’s usually a logbook to […]
