Blasting Cap

Blasting Cap is a trinket added in Afterbirth.

Effect

• Upon exploding, bombs have a very small chance to drop a bomb pickup.

Note

• With a gold bomb and a lot of patience, an infinite number of bombs can be generated.

Trivia

• The pickup quote, "Pop! Pop!", is most likely a reference to the character Magnitude from Community, who had the quote as a catchphrase.
• Another possible source is the character Yung Venuz or YV from Nuclear Throne who possesses an ability with the same name. Said ability allows him to fire two bullets at once instead of just one, similar to the trinket's effect.
