DIY Time Capsule Made of Repurposed Plastic Bottle
Are you planning to create a DIY Time Capsule, full of memories for a future moment? You are on the right page. Not only because there are tons of ideas, but because my version is helping the environment by reducing plastic waste – it’s made out of with a repurposed plastic bottle.

At the end of 2015, I had so many things going on in my life, I needed to gather my thoughts and bottle them up. When I realized, how great memories these days will be once, I decided to make my very own DIY Time Capsule. Since I didn’t want to spend any money on it, I just put everything in a bottle that was lying around. In other words, I repurposed a plastic bottle. Of course in general, it would be more important to stop using the plastic bottle and for this to happen, I gathered some alternatives I recommend using instead. Tons of other things can be repurposed in our homes, see them here.
How to make the plastic bottle look like a DIY time capsule
The whole thing could have been covered up or painted, so I wouldn’t see what’s inside, but I left it in the original form. My catch was the size of the bottleneck. But it was okay, I put only small things in it anyway. If I had wanted to put bigger things in, I would have just cut the bottle in half, and then taped it together at the end.
First, I did a lot of research, because naturally, I drew blank when I thought about things I needed besides my letter to myself. I wanted to put real interesting memories in this DIY Time Capsule, so I made quite a list by the end. It was a truly fun project. If you want to make a day of it, do it with kids, that’s even more fun for sure.
First, here are some great DIY Time Capsule note ideas that I collected, and put in my very own repurposed plastic bottle as memories:
Letter to myself:
- Goals, dreams
- Current stuff happening in life with me, my family, and friends
- Things that bother me
- What makes me happy, and tick
- How I will look in 10 years
- Everything that happened to me on the day before
Pieces of papers with just one or two words on them, which I rolled up, tied them with ribbons, and made some nice bows after writing on them:
- Close friend’s name
- Who I miss
- Current everyday habits
- Favorite flower, animal, smell, color, game, movie, music, etc
- Funny words
- Last food and drink I had

After all the writing, here are some ideas to slip into this almost perfect DIY Time Capsule:
– Recently collected pebbles, shells
– Nametag from the previous job
– Uniquely colored soda can tabs
– Bookmark
– An old medallion
– Photos
– Lucky charm
– A tiny dice
– Keychain
– Drawing of favorite animal
– Fridge Magnet – which I made myself with a piece of carton, glue, magnet and a tissue paper
– Money – a banknote and some coins
– Pressed flower
– Some current tickets from the movies, theater, concert, museum, party, festival, tour, etc – whatever I found in my pockets, purses, and on the fridge
When all the memories were inside, I sprayed some of my favorite perfume in the bottle and then quickly put the cap on. (Check out how to make fridge magnets with plastic bottle caps.)

Where did I put my DIY Time Capsule when I was done?
Of course, I didn’t want to dig a hole in the garden under the apple tree, not even for a repurposed plastic bottle and I didn’t seal it off with wax – although, both of these are great ideas. I just put it in my ‘memories box’ and marked the date in my calendar – in my case, 10 years later, 2025.
The whole point is to see how much I’ve changed in that bottled-up time.
Have fun! Whenever you decide to make one, I would be very happy to see a photo of your DIY Time Capsule, sent me a photo of it! And don’t forget, one repurposed plastic bottle is only a tiny step towards saving the environment, the main goal is to stop using plastic bottles entirely.
