The Ice Bucket Challenge has succeeded in raising millions of dollars for ALS research. It has also spread the word to millions, as many who do not donate still post the video and nominate their friends. 

However, not everyone is all too thrilled with the challenge. It has faced criticism for wasting water and others have lashed out against those who post the video without donating. One Wikipedia editor took it to the next level, leaving this message in the "Criticism" section of the Ice Bucket Challenge page:

For those, like this Wikipedia fellow, that hate the waste of water, there are a number of other challenges which might appease them, help a good cause, and preserve water. 

Ice might have started the craze, but now there's rubble, sand and rice. Different causes are getting behind the bucket challenge, all with their own unique bucket filler. Here's what else you might find in a bucket:

Rice 

The Rice Bucket Challenge is designed to help the hungry in India. Rather than pour water (or rice) over your head, the challenge encourages people to share a bowl of rice with someone who is hungry. 

Manju Latha Kalanidhi came up with the challenge. She told our sister site Quartz, "The idea of dunking oneself in icy cold water, shrieking in horror and then uploading the bizarre video felt preposterous. I wanted to just do something local, meaningful without wasting anything. So rice replaced water here. Response has been staggering. You can donate to any needy person—a poor kid, a vegetable seller, your maid, driver, watchman, orphanage etc."

So far, the challenge has over 21,000 Facebook Fans. 

Here it is in action:

Sand

Sunny California might be all for the ice bucket challenge, but the state is fining citizens for participating this summer, as they are experiencing a major drought. Instead of using water, California citizens use something they have plenty of: sand. 

And here we have the sand bucket challenge: 

Rubble

To raise awareness for the war in Gaza, a Facebook group was started for the Rubble Bucket Challenge. Using debris from bomb sites, people in Gaza are pouring it over their heads to spread awareness about the destruction of their homes and the war in general. 

It was started by journalist Ayman al Aloul, who told NBC News, "I have to do something and to send a message all over the world about Gaza." So far, the Rubble Bucket Challenge has several thousands fans on Facebook

Last but not least, the rubble challenge:
