Tech titan Elon Musk became the latest celebrity to complete the "ice bucket challenge" Saturday, aided by a delightful contraption that allowed his five sons to dump water on him simultaneously.
The challenge asks participants to either donate money to the ALS Association or film themselves pouring ice water over their head. Those who complete it then ask others to do the same.
Musk made good on a challenge from Bill Gates, who had himself been challenged by Mark Zuckerberg. In turn, Musk challenged Minecraft creator Markus "Notch" Persson, Johnny Depp and skateboarding legend Tony Hawk.
But Musk's impressive engineering has nothing on Oprah's scream.
Watch Musk complete the challenge, above.
