The Specter of the Panama Canal ( (まぼろし) のパナマ (うん) () Maboroshi no Panama Unga) is the one hundred-seventy fourth chapter of the Dr. Stone manga.


The team, tailed by the rest of the American Colony on the Perseus, need to collect rubber for motorcycle tires in order to cross South America. If they stop, they run the risk of being shot to pieces by Stanley's sniper rifle. As they know the recipe for the Revival Fluid, they have no reason to leave the Kingdom of Science alive.

Trying to find a solution, Taiju asks Ukyo if there's anything he can do with the radar, but Ukyo says the other man is elite and will notice even the smallest change.

Chelsea comments while standing on the deck of the ship that she wishes the Panama canal was still viable, prompting Francois to explain to everyone what the canal was. Taiju seems excited at the prospect of being able to use it, however Chelsea says it's probably been filled in. Senku and Ryusui then decide to split the team into two, 'team rubber trees' and 'team Panama canal'.

After a tearful farewell from Kaseki, Chrome, Suika and Taiju, they cast off the amphibious Mobile Lab, decorated in metal to be better seen by the radar on the Perseus, sending it in the direction of the canal on 'autopilot' (they tied the controls). The Americans on the Perseus notice the second signal on the radar, and are forced to choose which one to follow.

The rubber team then land on the shore, following Chelsea's advice. Sure enough, they find rubber trees which they immediately start tapping. While everyone is helping out, Gen offers Xeno a knife, asking if he wants to help. Xeno questions this, as Gen would be giving a prisoner a weapon, however Gen is convinced that Xeno would never "taint science with lies".

Using the rubber resin, adding vinegar and sulfur powder and then kneading and forming the result, the team produce several bouncy rubber balls. The chapter ends with rubber having been acquired.

Chapter Notes[]

  • The team sacrifice the mobile lab, in order to force Stanley into choosing which radar signal to follow.
  • The Kingdom of Science land on South American soil and are able to find rubber trees.
  • Gen tries to build trust with Xeno, but not enough to allow him use of their communication devices.
  • Rubber is made.


  • During the mobile lab's sendoff, Taiju's pose is a reference to the anime One Piece.
