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.

Underwater Metal Detecting a WATERFALL - I Found an iPhone, Rings, Pocket Knife (Phone Returned!!!)

WOW, this is BY FAR my favorite River Treasure dive so far. While scuba diving in an Arizona Waterfall with my metal detector, I found lots of amazing treasures, including a nice Pocket Knife, 2 Rings, Sunglasses, some Coins, and a WORKING iPhone 6s PLUS in a Waterproof Pouch (lost for 9 months, and still worked!). I was able to contact the owner and return the phone. His reaction was priceless, he was so thrilled to have his phone back in perfect condition after missing it for 9 long months!!! The Owner "Prince Ahmed" (as his friends call him) treated all 4 of the MAN + RIVER crew to dinner!

Water filled hot tubs are soooo 2016.
Go to http://bit.ly/CasperMarkRober and use promo code "MarkRober" for $50 off any mattress. They're super dope.

By popular demand I have shirts now! I picked the high quality shirts and make $0 on all items which is why they are priced handsomely.
