Orbeez space colorful, squishy small beads around the size of ball bearings do of polymers created of acrylic acid, sodium hydroxide and also water. Harper Park
In the year 2020, people likely spent much more time boring at residence than in any kind of other year because the revolve of the century. And it"s entirely possible that millions of homebound human being actually considered performing the complying with task:

Discover through the scientific an approach of trial and error how countless hydrated Orbeez the takes come fill your bathtub.

You are watching: How big can an orbeez get

While we applaud experiment of most kinds, us will carry out that mathematics for you below so you don"t have actually to damage your pipes finding out. Unless, the course, you desire to.

Orbeez start off together hard, colorful small beads around the dimension of ball bearings made of polymers written of acrylic acid, salt hydroxide and also water — the same stuff that renders diapers and maxi pads absorbent. As soon as submerged in water, the spaces between these polymers space packed complete of water molecules, bring about their swelling to a dimension over 150 times their original diameter. They also can it is in dehydrated — just set them in the sunlight or in a dry, open up container — whereupon lock shrink ago to their original size in a day or so.

So, how countless of this water beads would certainly it require to fill increase the bathtub at her house?

Bathtub size differ, but in the U.S. A standard bathtub holds 42 gallons (159 liters) that water. How countless individual water beads would certainly it require to fill whole tub?

According to the Orbeez website, 100 dried water beads productivity one cup (240 milliliters) of totally hydrated Orbeez. There room 16 cups in a gallon, and also therefore 1,600 water beads in a gallon. So, because that a 42-gallon (159-liter) bath tub you"ll need 67,200 water beads to fill a standard sized bathtub. But, be aware, that at almost \$24 because that a parcel of 2,000 Orbeez, the could price you a pretty coin to fill her bathtub. Over there are, of course, similar, less expensive choices on the sector as well.

But wait! If you"re yes, really going to try this in ~ home, remember that if you space planning to submerge you yourself in the bath tub full that Orbeez, you"ll displace a ton of swollen beads through your body, so perhaps shoot for around 30 gallons (114 liters) to be safe. In the case, you"ll need much more like 48,000 water beads. Suggest being, if you acquire in your Orbeez bath, you may not get any cleaner, however it will conserve you part money.

Final caveat: Orbeez flourish bigger if you usage distilled water. The salts and minerals in madness water inhibit the development of every bead, and some people put salt or rubbing alcohol in their beads to save them from cultivation bacteria, which also keeps castle from cultivation as large. Because that the best beads, usage distilled water!
