‘Mythbusters’ Prop Auction Will Benefit Grant Imahara Charity

As much as the incredibly long-running and fan-favoriteMythbustersseries sought to entertain us through the power of science, viewers of the show can back me up when I say that the true stars were the hosts:Jamie HynemanandAdam Savage, along with the “build team” surrounding them that would eventually be made up ofKari Byron,Tory Belleci, andGrant Imahara. Look no further than the unanimous outrage that rose up when the show had to scale down in later seasons and remove the latter three altogether. Sadly, tragedy struck in July 2020 when it was announced that Grant Imahara had suddenly passed away following complications from a brain aneurysm. The beloved figure was only 49.

But those closest to Imahara are ensuring that his legacy lives on and that fans will have the opportunity to remember him a little more tangibly.

Auction Details

Excitingly, every prop is an authentic product of the show and was built and tested by theMythbustersteam for use in actual episodes. Some of the highlights fans are sure to recognize include the working mechanical shark from the “Shark Week Special” in 2008, the"Robo-cat" built by Grant himself, surviving pieces from the famous test dummy “Buster,” and more.

Carolyn Imahara, Grant’s mother and co-founder of the non-profit released this statement:

“I’m so grateful for this opportunity to raise funds that benefit the Grant Imahara STEAM Foundation. I’d like to thank Discovery Channel, Beyond Productions and Prop Store for helping us bring these artifacts from Mythbusters – some of which were built by my son — to fans worldwide, while contributing to a cause very dear to Grant. I’m proud of the work the foundation is doing in my son’s name, and I’m thankful to all the fans and supporters who are helping us with our mission to inspire and empower young and underserved talent in STEAM education.”
