Mr Koinange had a bucket of water poured on him by Bishop Ron Archer, who was the guest on his "Jeff Koinange Live" TV show on Thursday.
After recovering from the shock of cold water running down his suit, Mr Konange announced that he would donate an undisclosed amount to the Beyond Zero Campaign.
He nominated radio presenter Maina Kageni, comedian Dan Ndambuki, aka Mwalimu King’ang’i, and Flossy Floss.
Mr Collymore literally added ice to a bucket of water and poured it on himself.
The Safaricom boss nominated former presidential candidate Peter Kenneth, who later took up the challenge, and musician Juliani.
Others who were previously nominated by Kenyans who have taken up the challenge include television presenter Julie Gichuru, radio presenter Adelle Onyango, Ronnie Osumba and Joshua Waigara.
HIGHEST NUMBER OF NOMINATIONS
Comedian Dan Ndambuki has received the highest number of nominations for the challenge locally.
The ice bucket challenge started early this year as a campaign to promote awareness of the disease amyotrophic lateral sclerosis (ALS) – commonly known as Lou Gehrig’s disease – and encourage donations to research towards finding a cure.
Out of the Kenyans who have taken up the challenge, only Mr Koinange, Mr Madowo and Mr Kenneth have announced donations to a local charity.
The challenge has received a lot of global criticism, with many people complaining that many who are nominated do not actually donate to charities and only take the challenge for fun.
There is a standard international way of doing the ice bucket challenge. Participants film themselves accepting the challenge, pouring cold water on their own heads and nominating others to do the same within 24 hours.
The nominated person is then expected to donate between $10 if they pour water on themselves and $100 if they don’t, but the amount is not limited to this.
More than $88.5 million has been raised so far towards ALS research in the challenge, which was first taken by former Boston College baseball player Pete Frates.
