Break the tunnel block with a Bomb and then return to safety. Break the runway block on the next cycle. SpringBall helps avoid acid damage. Bombing Samus up through the runway with a second Bomb can help, or it can trap Samus in the acid if liquid physics take effect.

Requires:

"h_useMorphBombs"
{
  "or": [
    "h_useSpringBall",
    {
      "acidFrames": 10
    }
  ]
}
{
  "or": [
    "canInsaneJump",
    {
      "and": [
        "canTrickyJump",
        {
          "acidFrames": 10
        }
      ]
    },
    {
      "and": [
        "canCarefulJump",
        {
          "acidFrames": 120
        }
      ]
    },
    {
      "acidFrames": 200
    }
  ]
}

Dev note: Damageless is possible without SpringBall but it is very likely you end up taking more damage by attempting it.
