How to make a Water Bead Sensory Light Box

You’ll need the following items to make your light box:

– Clear Tote (best size is 14″ x 11″ approx)
– LED light bar/flashlight strip (battery operated is best)
– Water Beads
– Large Ziploc Bag
– Duct Tape is best but you can also use packing or painter’s tape.

Let’s make our light box!

1 – Start by making sure that your clear tote is large enough. A flat ziploc bag should cover most of the surface like this example below.

Mesure the size of your bag to the size of your bin.

2 – Fill a large ziploc bag with enough water beads that when it lays flat, it covers the fills the whole surface.

3 – Grab your clear tote and add your LED light strip. LED is best as it’s super bright, as you can see here. It will give enough light for the beads to light up like little crystals. Your child will be mesmerized!

4 – Grab the bag filled with water beads and remove all air before closing it. That’s very important. If there’s too much air in the bag, they won’t be able to move the beads around as much. Once the air is out, lay it flat on the top of the box, as shown below.

Place the water bead bag flat on the top of the bin.

5 – We need to secure the bag in place. I would recommend taping the end opening of the bag first. You want to make sure it seals well. Once the opening is sealed, now start taping the bag all around the edges.

I prefer to use duct tape as its much more secure. You can use any large tape you have on hand.

Make sure that the tape doesn’t go below the edge of the lid. We need to be able to open the box so that we can turn off the light.
