DIY Floam




About: In a valiant attempt to keep myself from dying of boredom, I create.

Floam, my kids loved floam while that were young. Hard to find though. I found this recipe on Pintrest at: , I had it pinned under “preschool science”, and since I had my grandsons this week, and I had all the ingredients on hand, well why not. I will tell you about my funny grandkids when I am done.

Step 1:


2 tsp of borax (found on the laundry isle of your supper market)

1/2 cup of warm water

1/4 cup of warm water

2 oz. of white school glue (I haven’t used Elmer’s glue since they changed the formula, I have used other, cheaper brands)

1 & 1/3 cups of polystyrene beads (I have a huge bag left over from past projects, can be found where you can find supplies of bean bag chairs, if you can’t find any, you can grate up some Styrofoam cups)

Optional: 3-5 drops of food coloring if color is desired

Quart zip closure bag

Measuring cups

Measuring spoons



Step 2:

Measure out the 2 tsp. of borax powder into a bowl. Slightly rounded teaspoonful worked for a stiffer floam.

Step 3:

Add ½ cup of very warm water and stir until the crystals have all dissolved. Now for a comment about safety. Borax is toxic, and can be harmful if not handled safely. This part is for adults to handle. Be sure the equipment is totally cleaned before using again.

Step 4:

In another container, put 2 ounces of white glue and ¼ cup warm water.

Step 5:

Add food coloring at this point.

Step 6:

Stir with a different spoon, (to prevent cross contamination,) until the glue, water and coloring are completely mixed.

Step 7:

Measure out your 1 1/3 cups of the polystyrene beads and have them ready.

Step 8:

I eventually add enough beads to make 2 cups.

Step 9:

Pour the glue mixture into the zip closure bag,

Step 10:

add the polystyrene beads and finally the borax solution.

Step 11:

Quickly zip the bag closed and start squishing the 3 parts together until they become as one.

Step 12:

Now comes the funny grand kids part. I made three bags made in 3 different colors and my grandsons wouldn't touch it. It was yucky. Now I’m not so sure I want to make GLARCH (another form of slime, it can be great fun), for them, oh well, I sure had fun playing with it. Enjoy!

    The polyfoam pellets are not safe to eat. Sorry about that. Thanks for commenting.

    Maybe you should enter this in the remix contest? Since its a copycat recipe - If that's allowed though, since its from pinterest not instructables. I don't really know. Just a thought ;)

    Instructables that are to be entered into a contest needs to be published after the start of the contest. So this Instructable won't work for the Remix Contest. Now you know. Why don't you find something that fits the Remix guide lines and write and enter your own Instructable. It's lots of fun!

    Really??? I didn't know that. Well, thanks for letting me know but that kinda sucks :( Would you (in general) be able to remake a new instructable for a contest even if you already made one of the same thing?

    Then I need to do an Instructable on glarch (glue + starch). Liquid laundry starch is the starch. Thanks for commenting

    In step 3 I discussed that borax is toxic and should be handled by adults and not children. The finished floam is not eatable. Safe for age 8 and older. Thanks for commenting.

    I'd say 10 and up for kids.
    Borax is only poisonous in huge doses, the LD50 is 2.65g/kg, an average 10 year old would have to eat 3 of this recipe.

    But small doses would still make you feel sick, so an older kid that isn't likely to eat it.

    You might try making it with cornstarch based slime.
