Where do you get a powerful explosive bolt?

I try to launch a rocket, but there are no friends to add. How can I find a powerful explosive bolt to make numbers go all the way?

Edit: This is how it works in the Android game, I'm not sure how it works in Windows...

You can only add facebook friends, which makes the option to add friends to a launch completely useless (since none of my neighbors are in my facebook).
You can promote your launch in the launch group topic and ask others to join in. Or hope for random neighbors who see your launch to join.

You can get powerful explosive bolts by opening 'launch ready kits' which you can require by completing several launch collections (visit neighbors and collect from their launch platforms, mission control center, planetarium, training center, astronaut acedemy), or buy them with greens in Duke's airship.

Good luck Denearys!

Thank you ever so much for your advice.
Still, I wonder where you can "see" a neighbors launch?
I have never seen any.
Thank you again,
Sincerely,
Denearys.

Hi Denearys,
You first have to select a platform (green, blue, or red).  Once you select a launch pad, if you have a neighbor that has started a launch you will see it there.  You then have the option of joining that launch or starting a new one.  Once you select a platform you are committed to stay on that platform until you launch.  You don't have to start one right away, you can wait and keep checking to see if a neighbor has started one that you can join.
I hope this helps.
Cheers,
Sulfe
