Water Bead Ice Pack




Introduction: Water Bead Ice Pack

Make a flexible ice pack! Made of rubbing alcohol and water beads, this ice pack will get cold but never freeze! Perfect for icing joints such as knees! You can also make it fun colors! Let's get started!

Step 1: Get Your Supplies

To make a water bead ice pack, you will need to get some supplies.

You will need:
•package of water beads that makes 3- 3 1/2quarts (I found my in the floral section at Walmart)

•2 32 ounce bottles of 91% rubbing alcohol (Rubbing alcohol doesn't freeze at the regular freezer temperature. This is what makes the ice pack flexible)

•gallon sized freezer zip locks (make sure it's freezer zip lock so that it will not leak or burst when it's frozen)

You will also need a large metal or plastic bowl. Food coloring is optional if you want to make fun colors!

Once you have all your supplies, you can start making the water beads!

Step 2: Making the Water Beads

The actual ice pack is made of water beads and rubbing alcohol. To make the water beads, follow the instructions on the package. But, instead of just water, use 1/3 rubbing alcohol and 2/3 water. This will help make the water beads cold but squishy! An example of what my directions for the water bead were is pictured. Let the water beads sit for 4-6 hours or until they fully absorb all the water. You might need to drain them afterwards, just make sure all of the water is out of the bowl before you move on to the next step.

This is also where you can add food coloring for fun colors!

Edit: I used purple and blue colored water beads the purple water beads lost their color and turned clear. The alcohol turned purple in turn. Dunno why, but it's kind of cool!

Edit: The water beads also didn't absorb all of the Alcohol/water mixture. I had a lot left over. You can either use this in a latter step, or dump it down the drain. Up to you.

Step 3: Putting the Ice Pack Together

Putting the ice pack together is quite simple.

Simply drain the access, and put all of the water beads in a freezer zip lock bag.
After that, poor in 91% alcohol until it covers all of the water beads. The water beads should be slightly "swimming" in the alcohol. This is where you can use the access alcohol/water mixture. I don't recommend it, but go for it!
Then close the zip lock while making sure to squeeze out all of the air. Be careful not to squeeze out the alcohol and water beads as you do this!
I put the zip lock in another zip lock just to protect against leakage. You should probably do that too . . .
When all of this is done, you can freeze it!

Step 4: Freeze the Ice Pack

This is the hard part! Waiting for it to freeze! Lol! Place the ice pack in the freezer and wait.
2-3 hours pass by, and Voila! You have a flexible ice pack!

Step 5: Use the Ice Pack

The ice pack is now ready to use! Hope you enjoyed this tutorial! It's my first one, so I'm still experimenting! :) I'm not going to ask for likes or follows or anything, just be nice and enjoy!

    can this be re-used and frozen again?

    Yep! Rubbing alcohol freezes at an extremely low temperature Spit will be as cold as water but not frozen solid.

    Is the bag still pliable after it is frozen?
