You do not bend glass by forcing it. You warm it until it agrees, and the light comes later. The Babolat Stage 1 Green is exactly that judgement in a tennis ball: a full-size ball at roughly 25 per cent lower compression than a standard yellow one, marked with the green dot, three to a can.
It flies a little slower, sits a little lower, and lets a young player actually finish a swing on a full court instead of chasing shoulder-high bounces. Nagasaki, which knows more about light than any town I have worked in, would understand the argument immediately.
Start at the Nagasaki Peace Park, north of the hypocentre of the bombing of 9 August 1945. Seibō Kitamura's ten-metre bronze has been seated there since 1955, right hand raised toward the threat from the sky, left hand out flat for peace, and a black stone monolith marks the point over which the plutonium bomb detonated.
A fountain nearby remembers the people who died calling for water. Every year on the anniversary the city stops at 11.02. There is no clever way to describe this place and I am not going to try.
Then up the stone stair on the hillside to Ōura Church, small, white, Gothic, finished in 1864 by French missionaries and dedicated to the twenty-six Christians crucified in Nagasaki in 1597.
Weeks after it opened, villagers came to Father Petitjean and revealed that their community had held Christian belief in secret for some two hundred and fifty years without priests, sacraments or scripture. It is the oldest church in Japan.
Along the same slope, Glover Garden gathers the white timber merchant houses of the treaty port around the residence of Thomas Glover, and below all of it sits Dejima — the fan-shaped artificial island where Dutch traders were confined, and which for two centuries was the country's only window onto Europe.
Land reclamation swallowed the water; the warehouses have been rebuilt to their nineteenth-century form, and there are plans to give the sea back.
You will run this can everywhere from a municipal court above Nagasaki harbour to a school hall in Fukuoka, two hours north, and by the way, it is also perfect for the walk up to Glover Garden afterwards, which is all slope and outdoor escalators and is, like this ball, deliberately easier than it looks.
