To use your Flinging Slingshots, you must first activate them. There are two ways to do so:
1. Visit your inventory. Once in your inventory, click on your Flinging Slingshot pack and select “Activate Flinging Slingshot.”
2. If you purchased your Flinging Slingshot pack from the Free the Faeries page, you can activate it right after purchase. Once you see the confirmation page, simply click the “Activate Now” button and confirm the use of your pack.
Once you have activated your pack, you can visit the Free the Faeries page and click on a bottle to break it.
