How do I make a Secret Potion in The Gold Factory Game?

I know to look in the game files but I can't find it.


It appears to be:

1 gold bar, 1 iron bar and 1 health potion respectively

as seen in base.js:

else if(cldr[0]!=null && cldr[1]!=null && cldr[2]!=null && cldr[0].id=="goldbar" && cldr[0].quantity==1 && cldr[1].id=="ironbar" && cldr[1].quantity==1 && cldr[2].id==7 && cldr[2].quantity==1)

The item with ID 7 being a

health potion

As can be seen from the line:

items.push({"name":"health potion","price":50,"owned":0,"plural":"s","showstorage":true}); //7
