25 Million Orbeez in a pool- Do you sink or float?

Kevin (aka The Backyard Scientist) and I filled a pool with 25 million waterballs (aka Orbeez) so I could settle an argument about how far you sink if you jump in.

****************************************­

I make videos like this once a month all year long while supplies last:

[GuavaJuice]

Please tell me how you cleaned all this. It took forever for me to clean just a bathroom full of Orbeez.

I can't imagine the magnitude of cleaning a pool. I feel your pain.

Mark Rober takes random thoughts that pop into your head at 3 AM as you contemplate life, and actually tests them for people's entertainment. What a legend.

[blokvader]

Mark Rober: 25 million orbeez in my pool!"
MrBeast: Interesting

[xcOfficial]

7 years and he is still trying to become the greatest uncle

“*relax, your horse will float*”

-Mark Rober

[deepmalakant]

*after experiment
Kevin:let's clean up this mess.

Mark has left the chat

[Murderbot-]

This man just solved every child’s fear of quicksand

[WandaOyola]

That looks so much fun!! Seeing those smiles was worth the experiment!

[overbonked]

Mark: So am I your favorite uncle?
Kids: no
Mark: filling a pool with lava and dunking my nephews

[TheLazyGamer]

this guy has the imagination of a child and it's so fun to watch it unfold

[yice]

Everyone’s talking about the quest to be the favorite uncle, but all I think about is how lucky those nephews are 😂

[automotivel]

Mark you are, without doubt, the coolest uncle.

[manlikeform]

“Relax your horse is gonna float”

- uncle of the year

[daisythealaskan]

I can imagine his nephews growing up and eventually have someone ask them “What’s the weirdest thing that every happened to you?” And they simply reply “ I was eaten by a pool of orbeez.”

[comradestradaniya]

To-do list:

-get 1, 000, 000 dollars
-buy a mansion
-be Mark Rober’s nephew

[ABABABABBA.]

7 years later and this still give me joy

[moonsgrave]

“Relax, your horse is gonna float!” - Mark

[harrisonpickard]

You are definitely the favourite Uncle.

[ejvaz]

I want to know the way he goes about cleaning after a lot of his projects.

[lonelyking]

My theory for what would happen when you jump in a pool of orbeez was that how far you’d sink depended on what position you fell in, as in whether you landed on your back or feet, and your weigh, because of gravity.
