Rain: research

To fully understand the concept of rain, I decided to do some initial research into the meaning, and various phrases that are used to represent rain. Here are some of my findings:

Definition from Oxford Dictionary. 

Rain  noun

[mass noun]

• the condensed moisture of the atmosphere falling visibly in separate drops:

  the rain had not stopped for daysit’s pouring with rain
• (rains) falls of rain:

the plants were washed away by unusually heavy rains

[in singular] a large or overwhelming quantity of things that fall or descend:

he fell under the rain of blows

verb

[no object] (it rains, it is raining, etc.)

• rain falls:

  it was beginning to rain
• literary (of the sky, the clouds, etc.) send down rain:

the low sky raining over tower’d Camelot

[with adverbial of direction] fall or cause to fall in large or overwhelming quantities:

[no object]:

bombs rained down

[with object]:

she rained blows on to him

[with object] (it rains ——, it is raining ——, etc.) used to convey that a specified thing is falling in large quantities:

it was just raining glass
The Oxford Dictionary also provided common phrases that are about rain and this has given me an idea for the copy of the poster- to possibly looking at existing words and phrases about the theme and turn them positive with simple alteration. This will confuse the audience if the phrase is well known and make them view the poster again to notice the difference. Unless the phrase works without.
