Blue Prince: All Contraption Interactions

In Blue Prince, you can unlock both temporary upgrades that fade at the end of the day and permanent upgrades that continue day after day. Some permanent changes are things like adding new floorplans, upgrading rooms, and more.

Several of these permanent upgrades require different items that must be crafted using a Workshop in Blue Prince. If you want to make sure you complete all the possible interactions while you have one of these items available, this article will help you out.

All Crafting Recipes at the Workshop

There are a grand total of eight items you can build in the Workshop in Blue Prince, and three of these can be used to make permanent changes to your game. Below is a breakdown of how to make the items, as well as where each of these interactions will need to take place.

Power Hammer Interactions

A Power Hammer is made with a Broken Lever, a Sledgehammer, and a Battery Pack. This more powerful hammer is capable of breaking down walls, unlocking new areas and shortcuts. These will not go away between days.

Inside the Freezer: In the back left of the Freezer room, there is a sheet of ice covering part of the wall. You can break this down with the Power Hammer to see what’s hidden inside; there are also plenty of frozen items on the shelves that you can break out.
A Shortcut to the Basement: If you head down the front steps of the house and go a little bit to the left, there is a stone staircase heading down to the platform with Blue Flames in Blue Prince. To the right, at the bottom of the stairs, is a doorway covered in planks; these can be power-hammered as well. There will be another door at the end of this tunnel to break down. It goes into the Basement.
In the Crate Tunnel: According to user Forblaze on the Steam community page, there is also a breakable wall at the back of the “crate tunnel” once you move the crates out of the way.
The Weight Room: The Weight Room is a four-door red room you can draft inside the house. There is a hanging punching bag with a brick wall behind it. This can be taken down with the Power Hammer to give you access to a lever for Blue Prince‘s Antechamber.
The Secret Garden: If you head toward the far end of the Secret Garden where you find the Weathervane puzzle and the large silver crescent moon decoration, there will be a breakable wall to your right.
Greenhouse Wall: The Greenhouse is a Dead End floorplan in Blue Prince that can be permanently altered with the Power Hammer. Head inside and turn to your left, away from the flowerbeds. There will be a brick wall that is breakable that alters this floorplan to have a second door.
Secrets in the Underpass: If you access the underground on the far side of the Reservoir via the Blue Flame elevator or the Boat, you can find a dirt hallway with a chess puzzle on a pedestal. To the right of the entrance to this room is a crack in the wall that can be broken with the Power Hammer to reveal a clue for another puzzle.

Burning Glass Interactions

Burning Glass in Blue Prince can be made by mixing a Magnifying Glass and a Metal Detector. It is used to light candles, torches, and certain surfaces, unlocking new locations and clues.

The Freezer: You can use the Blue Prince item, Burning Glass, to melt the same patch of ice inside the Freezer that can be broken by the Power Hammer. You can also use it to break out any objects on the shelves, like gems, keys, and the note in the deep freezer.
In the Chapel: There are two large candlesticks on either side of the altar in the Chapel; if you light these, you will find a little piggy bank underneath.
The Tunnel: There is a crate-filled tunnel on the Grounds by the Blue Flame platform. Inside are two unlit torches on the walls. Light them with the Burning Glass to unlock a new floorplan.
Twice in the Tomb: There are four candlesticks inside the Tomb, which is a floorplan that can be drafted in the Outer Room section behind the west gate. These two pairs will give you some lore and another Puzzle Box.
In the Crate Tunnel Again: The user Forblaze on the Steam community page also states that there is a set of candles at the end of the “crate tunnel” as well.
Reservoir Room: When you enter the underground Reservoir, you will find a room with a circle of candles surrounding an altar. If you light all these candles with Burning Glass, the floor will turn into stairs.
Blow Up the Trading Post: You probably have noticed the TNT in the Trading Post that you can draft outside. You can light this with Burning Glass, which will blow up the wall and give you some lore and some gold coins.
The Sundial in the Orchard: When you open up the gate in front of the orchard on the east side of the house, you can use the Burning Glass on the sundial.

Jack Hammer Interactions

The Jack Hammer is made by putting together the Shovel, a Battery Pack, and the Broken Lever. It’s extremely useful for acquiring additional items by digging up dig spots in and around the house. However, there is also one permanent reaction you can get with the Jack Hammer. If you take it into the gem mine, you can collapse the entire structure, which means you will lose the daily two-gem buff forever. It won’t collapse each time you use it, but it’s probably not worth the risk of trying it just for some Blue Prince gems.
