"I checked out a rolling drum invention for transporting water, similar to those used in holiday camps in Britain.
The Hippo Water Roller carries about 90 litres, is quite cheap and lasts up to 7 years.
It will be of good use to people who have to carry water a long way to their house. Like the water tower there is advertising on the Hippos which brings down the cost of them."
"After all that pump action, we did spot of shopping, had some lunch, then it was time to go to the Sandton Conference Centre - where most of the talking at the Summit happens."
Rhys:
"I joined in a good discussion about making Wales sustainable country, but I wasn't happy with what was said.
After listening intensely I realised the discussion was on what we were going to do in Wales when we arrive home.
The delegates were saying what they wanted from the Welsh Assembly.
I saw this as a waste of time as I believe this could easily be talked about back home. The main focus should have been the World Summit here in Johannesburg, after all that's what we have come to discuss.
Instead they carried on questioning the First Minister of Wales on their request.
Yes, I do believe this is important but we have come here to help poorer countries, and we can discuss our country back home.
After all Tony Blair has not come to address the world on what he wants to achieve in Britain but what he wants in the world!"
