We Made the World’s Largest Bath Bomb!

We Made the World’s Largest Bath Bomb!

Dropping this bath
bomb into your tub turns all the water
in your bathtub black. But how big would
the bomb need to be to black out an
entire swimming pool? Let’s try 2,000 pounds. So to make our
large molds, we’re going back to our old
friend, fiberglass, which we used to make the bowl
from our marshmallows video. We’re going to make
two halves that’ll come apart and hopefully
reveal a giant bath bomb. This epoxy just soaks
into the fiberglass and makes everything rock solid. Ta-da! Right behind me, there, is 31
50-pound bags of materials. The recipe is one part
cornstarch, one part citric acid, to two parts baking soda. And then we add the
dye to turn it black. That’s your regular bath bomb. We’re making one
a tad bit bigger. Once we get this
first batch done, there’s, like, seven
or eight more to go. So that’s good. Not bad for a day’s work, right? I’m putting this
in the sun to bake. I’ve got to dry this sucker out. I’m so glad I started rolling. Did you drop it in there? I got this, guys. We’re done! We’ve completed the bath bomb. Now we wait till tomorrow
and we try to figure out how to get it out of the mold. We’re going to cut all of the
shell off and all the support. We’re going to kind
of tip the back end and let the whole thing
roll into the pool. Ah. That’s one big bath bomb, y’all. [SCREAMING] That was crazy. Look how green it looks. Get your own black bath bomb

to see a little bit more about how we put this
whole thing together, head on over to,
where we have exclusive behind the scenes footage. Do you guys think this counts
as my bath for the day? Yeah, you’re swimming, man. Yeah. Yeah.
