Bottled water.
Why not try this on a hot day.
Hit your high street with bottled cold water (chilled if possible).
Simply ask passers by if they would like a water and if they do let them have one.
When they ask who you are or why you are doing it tell them where you are from and that you want to bless them because God has blessed you, or something along those lines.
The great thing is anyone can do and it can be the start of other things when they have been boosted by how God has used them.
