たいようのいし - Evolution Item
ある特定のポケモンを進化させる不思議ないし。夕陽のように赤く輝く。
Special evolution items like the たいようのいし first arrived back with the second generation of Pokémon, and are now required when evolving Pokémon such as キマワリ and キレイハナ and キレイハナ and エルフーン and ドレディア. When evolving these Pokémon, this item is required in addition to the candy, and is consumed when used.
How to evolve ヒマナッツ into キマワリ
In order to evolve your ヒマナッツ into キマワリ, you will need to have a たいようのいし with you in your bags. You will also need to have all 50 candy, in the same way as with a normal evolution.
On your ヒマナッツ pokémon's screen, select the evolution through the usual in-game menu. The たいようのいし and candy will be consumed, and you'll have a new キマワリ with hopefully all the right moves.
In Pokémon GO, evolving ヒマナッツ into キマワリ is a lot simpler than some of the other Pokémon games which required your Pokémon to also be traded to another player for the evolution to take place.

How to get the たいようのいし
The たいようのいし is obtained from spinning Pokestops and Gyms. There is a very low drop chance of around 1% per spin to receive a たいようのいし or any of the other evolution item, and there is an equal chance of obtaining each of the 5 currently available items.
There's no way to ensure that the たいようのいし will drop, but with only 4 other items, there's a greater than 50% chance that you'll receive one once you've spun over 250 Pokéstops.
The 7th day streak bonus gives you a very high chance of obtaining one of the evolution item, but it's not believed to be guaranteed.
