If you have been pulling your hair out trying to figure out how to craft RDX How to Make an Atomic Bomb in Your Garden, you are definitely not alone. Developer karahan's absurd backyard simulation game is filled with dark humor, but the mid-game progression wall is no joke. To successfully prepare the explosive mixture, you cannot simply dump the ingredients into the cooking pot. You must first combine the base precursors, pick up the flask, shake it vigorously, and then place it inside the freezer. Only after the liquid is chilled will the game allow you to transfer it to the pot.
There is a thin line between an immersive sim and a frustrating physics sandbox, and this title gleefully dances on it. Released in June 2026, the game tasks you with raising funds, ordering sketchy parts on the dark web, and physically hauling them into your yard without alerting the authorities. But the true enemy isn't the government—it's the game's own crafting UI.
Because the game currently lacks a mid-stage save feature, failing the chemical mixing step or experiencing the notorious "cannot add to pot" UI block forces a complete restart of the level. This guide breaks down the exact mechanics required to bypass the progression blocker and successfully deploy your explosive plates.
The Context of Stage 2: Demon Cores and Physics
Before you even reach the chemical mixing phase, you have to survive the backyard logistics. Transporting raw materials from the front driveway to your hidden assembly station is an exercise in patience. You are regularly tasked with lugging 30+ boxes across the property.
Prior to Patch 1.0, the wheelbarrow was a chaotic entity. Players reported it spinning aggressively across the fence or clipping through the terrain and flying under the map. Dropping the Aluminum bar crate into the tub caused severe FPS drops, turning a simple delivery run into a stuttering slideshow. Developer karahan recently tweaked the gravity and collision to reduce the movement of small objects, but the physics engine still demands respect.
Once you have the materials secured, the game shifts into a highly specific, punishing crafting simulator. You must monitor the Demon Core mass carefully. The recent update finally added the ability to check the core's mass before committing items to the assembly, saving countless runs from premature failure. But even with these UI improvements, the game refuses to hold your hand.
Step-by-Step: how to craft RDX How to Make an Atomic Bomb in Your Garden
The actual process of synthesizing your materials is where most players hit a brick wall. The game relies on tactile, physical interactions rather than simple menu clicks. Follow this exact sequence to avoid hard-locking your run.
Phase 1: Procurement and Staging Ensure all your precursor chemicals are unboxed and resting on a stable surface. Do not leave items in the wheelbarrow during this phase, as physics jitters can still cause materials to vanish unexpectedly.
Phase 2: Combining the Precursors Follow the whiteboard instructions to combine the base precursors to create the RDX mixture. At this point, you will have a glowing flask in your hands. Do not approach the stove yet.
Phase 3: The Agitation Phase Next comes the hidden mechanic that trips up 90% of the player base: you must shake the flask vigorously. Move your mouse rapidly while holding the interact button until the liquid visually changes state. The game originally suffered from missing instructions regarding this exact step, leading to massive community confusion.

Phase 4: The Freezer Bypass Once agitated, do not try to pour it. Instead, carry it into the kitchen and open the freezer. Place the flask inside and close the door. Wait a few moments for the internal temperature to drop. This chilling period is a hard-coded requirement to stabilize the volatile compound.
Phase 5: The Pot Transfer Retrieve the frosted flask. You can now safely transfer the cooled liquid into the pot. The UI prompt will finally turn green, allowing you to finalize the explosive plates and move on to the final assembly of the stage.
Why the Pot Bug Ruins how to craft RDX How to Make an Atomic Bomb in Your Garden
The frustration surrounding this specific mechanic stems entirely from the game's unforgiving save system. Navigating the mid-game requires balancing Suspicion Levels from nosy neighbors and federal agents. If you trigger an alert, or if the pot bug halts your progress, the lack of an autosave means a complete Stage 2 restart.
You must carefully deploy each explosive plate and monitor the Demon Core mass to avoid a total run failure. When players spent 45 minutes carefully managing their funds, sneaking 30+ boxes past the fence, and assembling the core, only to find they couldn't pour a flask into a pot, the Steam forums erupted.

The issue was compounded by localization and translation errors in the initial launch build. Players using non-English clients received completely blank instruction sheets for the chemical mixing phase. While Patch 1.0 addressed the missing text, the physical requirement to shake and freeze the item remains a mandatory gameplay loop.
Optimizing Your Backyard Setup for Patch 1.0
If you are returning to the game after a failed launch-day run, the mechanics have been smoothed out significantly. Understanding what was fixed will help you avoid over-compensating for bugs that no longer exist.
| Mechanic | Pre-Patch State | Post-Patch 1.0 State |
|---|---|---|
| RDX Instructions | Missing or mistranslated, causing the pot bug. | Added missing instructions; freezer step clarified. |
| Wheelbarrow Physics | Spinning across the fence, flying under the map. | Tweaked gravity; reduced movement of small objects. |
| Aluminum Bar Crate | Caused massive lag and FPS drops. | Optimized collision, resolving frame drops. |
| Explosive Plates | Materials vanished when placed in the wheelbarrow. | Fixed vanishing bug; plates are now fully deployable. |
| Demon Core Mass | Blind placement leading to critical errors. | Added UI to check mass before placing items. |

Even with these fixes, you should still treat the physics engine with caution. Never sprint while carrying the Aluminum bar crate, and always place your explosive plates on flat terrain to prevent them from clipping through the grass.
FAQ about how to craft RDX How to Make an Atomic Bomb in Your Garden
Why won't the game let me add the RDX mixture to the pot? You are encountering the Stage 2 progression block. The game requires the compound to be stabilized first. You must pick up the flask, shake it manually using mouse movement, and place it in the kitchen freezer. Once it is chilled, the pot will accept the mixture.
Can I save my progress during Stage 2? No. Saving is only done upon stage completion. There is no mid-level autosave or quicksave feature. If you encounter a game-breaking bug or fail an objective, you must restart the entire stage.
How do I retrieve a wheelbarrow stuck in the floor? If your wheelbarrow clips under the map after you exit the assembly station, there is currently no "unstuck" button. You will have to restart the stage. However, ensuring you do not overload the tub with the Aluminum bar crate significantly reduces the chances of this glitch occurring.
Why are my explosive plate materials vanishing? If you are playing on version 1.0 or later, this should be resolved. In the launch build, placing plate materials directly into the wheelbarrow caused them to despawn. Always update your game client before attempting Stage 2.
Surviving this absurd backyard simulator requires patience, a steady hand, and a deep understanding of the game's quirky logic. By respecting the freezer mechanic and taking your time with the physics engine, you can successfully navigate the mid-game hurdle and complete your atomic masterpiece.
