How To Make A Glitter Tumbler With Floating Confetti

I want to show you how to make a liquid filled, glitter cup.

I had an Etsy shop a few years back. Not only did I sell glittered cups online, but I also sold glitter epoxy tumblers to coworkers and everyone else that wanted one. I had custom tumblers for sale to anyone that would buy them, and I sold a TON.

Although I have since retired from making DIY epoxy glitter tumblers, I had an idea a few days ago, when Kennedy and I were in Starbucks. What if you could fill a cup with floating glitter?

Glitter Tumbler Supplies

To make this DIY glitter tumbler, here’s what you’re gonna need:

• Double Walled Clear Starbucks Cup With Straw or
• Double Walled Slim Water Bottle
• Vegetable Glycerin
• Tape (I used a sticker, but only because I didn’t have tape)
• 2 part Gorilla Glue
• Drill (Men always say Craftsman is the best, but IDK)
• 3/16 drill bit (I have this set and use it for everything)
• Glitter (I used this star one and a colorful one like this)
• Syringe
• Water

How do you make glitter tumblers?

Here’s how:

Step 1:Drill a small hole in the bottom of your tumbler.

You have to be precise with this. You can’t drill too far because if you do, your drink will permeate into the floating glitter section. We are only drilling through the first layer of plastic. I used a 3/16 drill bit. If you don’t already have this bit, just go ahead and get this set. You’ll save money in the long run, and you’ll find use for each piece. I can’t even tell you how handy owning a drill is.

Step 2: Tap glitter into the hole.

This takes a minute. It’s faster it you tap the cup on the table as you go.

Step 3: Pour in the liquid to make the glitter float.

Don’t be like me. Get you a syringe. I didn’t have one, so I filled an old eye drop container with the liquid.

For the glitter to have a good “float,” fill up a little over half of your cup with water. When it’s slightly over half full, fill it up the rest of the way with vegetable glycerin.

Although I eyeballed my water to glycerin ratio, it may be best to measure and mix it beforehand. If you use too much glycerin, the glitter seems to get “stuck” and clump together. If you use too much water, all of the glitter will fall to the bottom.

You need about 60% water, 40% glycerin.

Step 4: How to seal your glitter cup

Use a heavy-duty clear tape to close the hole you drilled. I couldn’t find my tape, so I used a lucky pig sticker instead.

…then use the epoxy to seal the tape.

No need to cover the entire bottom. Just use enough so that the tape becomes permanent.

This Gorilla Glue Epoxy is the secret ingredient to these cups. I love how easy this is to use!

When I use to mass produce glitter tumblers, I would mix up so much epoxy. The measurements had to be PERFECT- or else the resin wouldn’t cure. With this Gorilla Glue, you end up using just the right amount, which is why I love it for a small project like this. Plus, it cures faster than any epoxy I’ve ever used. There is nothing that works better, in my opinion. Plus, there’s even a mixing tray built into the packaging. How convenient is that?

Mix thoroughly for about 20 seconds, then spread it over the tape. (or pig sticker, haha.)

How to Seal Glitter Tumbler Without Epoxy

I promise, this Gorilla Glue will be less intimidating than sealing your cup with traditional epoxy; however, if you don’t have any epoxy on hand, you could potentially fill in the hole with a bunch (like, literally fill the entire bottom of the inside of the cup) with hot glue and place a waterproof decal on the bottom outside of the cup to really seal the glitter in.

I would not recommend this though, because I have never tried it.

Step 5: Enjoy Your Confetti Filled Tumbler!

I love how this liquid filled, glitter cup turned out! I almost looks like this Starbucks Cup is filled with confetti! While I don’t necessarily want to go back to the good ol’ Etsy days, (I would literally stay up all night trying to keep up with the volume of orders I had going out) I am thankful that God gave me a way to make money during a challenging time in my life. Plus, I can help you guys! I sold other DIY items on Etsy, so if you have any questions about that, let me know in the comments and I’ll be happy to help you out.
