I've been trying to trap liquid in resin and I finally did it successfully!


Learn how to make a liquid resin coaster! See above for the quick video tutorial, so you can see exactly how I did it!

You need to find clear straws and cut them to size, to fit into the coaster mold.

Using a lighter and pliers, you need to melt one end.

Then using an eyedropper, partially fill up the straw with water that is colored with food color.

Seal the other end the same way - with the lighter and the pliers. Then repeat with the other straws and colors.

Pour one ounce of resin into the mold. Pop bubbles with a lighter.

Then start to add your filled straws.

Let that cure a minimum of 12 hours. By allowing it to cure, it will keep the straws in place, so they won't float when you add the next layer of resin.

Then add one to two ounces of resin.

Pop the bubbles and allow it to cure at least 12 hours.

Then you can remove it from the mold and the liquid moves around in the straws!

    Love this craft! Looks easy enough for even me to do this! Where do you purchase the forms to make the resin coasters?

    Im asking the same question as GmaB. What do I use for a mold? Or what can I use for a mold? Does it have to be a silicone mold?

      It looks to me like the molds are just silicone baking "pans" like for cupcakes, etc. You can find them in a variety of shapes on Amazon, Walmart, etc. I have heart-shaped ones for Valentine's Day.

    first, there is no link in description to see technique used for liquid phone case, second, did you use anything besides water to mix w food coloring, because when I do this, and seal both ends, the colored water does not move around in the straws....so what gives, what am i doing wrong.

    Thank you for the video, because otherwise I don't think I will be able to do it. I am so excited to try this. This looks like a really fun Diy project.
