This project was so much fun. I’m so glad I did it. That being said, I doubt I’d ever do it again. But it’s totally worth it. Here is how we did it and what we learned along the way:
- Collect over 500 half gallon, cardboard containers. If you get about 520 to 530 that should be more than enough with some room for error.
Notes: Fake stuff smells the worst. Year old soy products, coconut milk and lactaid milk smells even worse than year old egg nog. You’ve been warned. Also, most people don’t use half gallons, so get as many people collecting for you as possible. If you think that on trash night you can go recycling bin-to-recycling bin and find half gallons, don’t waste your time. People just don’t use them. Find your friends, family and local businesses that do and ask them to collect them for you.
2. Rinse them out and open the tops.
Notes: I didn’t rinse all of them, which I came to regret. And the ones I opened froze faster and were easier to fill and carry. It’s more work in the beginning, but will pay off in the end.
3. Fill with water and a little food color. Fill to the fold line.
Notes: You will eventually need a few smaller ones so if you make about 15 that are half to three-quarters full, you’ll use them
4. Wait for a combination of snow and freezing temperatures.
5. Leave somewhere level and cold where they can freeze.
