The secret to making explosive plates in How to Make an Atomic Bomb in Your Garden isn't about the recipe—it's about where you craft. To successfully combine a Water Barrel and TNT without them falling through the floor, you must perform the crafting on top of the large, central workbench in the Stage 2 laboratory, not on the ground. This single change bypasses the game's notorious physics bug and is the only reliable way to create the plates needed to advance.
This guide breaks down the exact procedure, the reasons behind the common glitches, and how to reliably overcome one of the game's most frustrating hurdles.
What Are Explosive Plates and Why Do You Need Them?
In the context of Stage 2, the "Explosive Plate" is a makeshift breaching charge. Its sole purpose is to blow open the heavily reinforced steel door that blocks your progress deeper into the facility. You can't shoot it open, you can't pry it open—only a crafted explosive will do the trick.
The recipe itself is simple, consisting of two components found within the lab area:
- 1x Stick of TNT: The primary explosive charge.
- 1x Water Barrel: Acts as a focusing agent and container, turning a simple explosive into a shaped charge capable of breaching the steel door.
Without successfully crafting at least one of these plates, your run in Stage 2 comes to a complete halt. The challenge isn't finding the recipe, which the game makes obvious, but executing the combination in an engine prone to physics errors.
The Step-by-Step Crafting Process That Actually Works
Forget what you've tried. Dropping items on the floor is a recipe for disaster. Follow this precise sequence on the correct surface to guarantee success every time.
Step 1: Secure the Ingredients
First, you need the parts. Both are located in the main laboratory where the reinforced door is situated. You don't need to venture far.
- The TNT: Look for a small, open crate on a metal shelving unit, typically against one of the walls. Inside, you'll find a single red stick of dynamite labeled "TNT." Pick it up.
- The Water Barrel: In a corner of the same room, you'll find a blue or grey Water Barrel. Unlike the TNT, this is a physics object you must pick up and carry using the appropriate interaction key. It will slow you down while you're holding it.
Make sure both items are accounted for before proceeding. You can't initiate the craft without both in your possession or immediate vicinity.

Step 2: Choose Your Crafting Surface (This is the Secret)
This is the most critical step. The game's physics engine has a persistent bug where certain floor surfaces lack proper collision for dropped or combined items, causing them to clip through the map and be lost forever. Trying to craft on the floor has a near-zero success rate.
The only consistently safe surface is the large, metal-topped workbench in the center of the laboratory.
This workbench is a static, complex object with reliable collision detection. The game treats it as a solid platform, preventing items from falling through. Do not use any other table, crate, or patch of floor. Carry the Water Barrel to this specific workbench.
Step 3: The Correct Combination Order
With the right location secured, the order of operations ensures a smooth craft.
- Place the Water Barrel: While standing next to the central workbench, place the Water Barrel directly on top of it. Ensure it's stable and not teetering on the edge.
- Add the TNT: With the barrel in place, select the TNT from your inventory and interact with the barrel. The game should immediately trigger the crafting animation.
If successful, the two items will disappear and be replaced by a single, flat, circular object: the Explosive Plate. It will appear on the workbench right where you crafted it. Pick it up, and it will be added to your inventory, ready for use on the reinforced door.
Common Bugs and How to Avoid Them
This puzzle is infamous for its glitches. Understanding them is key to not losing your mind (or your precious TNT).

The Dreaded Floor Glitch
The primary issue, as detailed above, is a clipping bug. Dropped items, especially those created through a crafting event, often fail the engine's collision check with the floor plane. The result is that your newly crafted plate, or the ingredients themselves, simply vanish downwards into the void. Reloading a save is the only way to recover your lost items.
- Solution: Never, ever craft on the floor. Use the central workbench exclusively. This simple discipline solves 99% of the problems players encounter on this puzzle.
"Ingredients Won't Combine" Error
Sometimes, even with the items in the right place, the crafting prompt won't appear. This is usually a state issue with the game, not a bug with the location itself.
- Troubleshooting Steps:
- Reposition: Pick up the Water Barrel and place it down again in a slightly different spot on the workbench.
- Check Proximity: Make sure your character is standing right next to the workbench when you try to add the TNT.
- Reset the Room: If it still fails, leave the laboratory and re-enter. This can sometimes reset the scripts for the objects in the room.
- Reload Save: The last resort. Save before you attempt the craft, and if it becomes unresponsive, reload and try the sequence again from the beginning.
Advanced Tactics: Making Multiple Plates Efficiently
While you only need one plate to open the main door, you might want a spare or need to craft another if your first attempt fails and you have to reload. The components do respawn, but on a timer.
- TNT Respawn: The stick of TNT is the limiting factor. It respawns in its original crate location approximately every 5 real-world minutes.
- Water Barrel: The barrel is a permanent fixture and does not despawn or respawn. It will be where you left it.
If you need to make multiple plates, the most efficient method is to create a loop:
- Grab the first TNT and Water Barrel.
- Craft the plate on the workbench.
- Use the plate on the door (or store it).
- Set a 5-minute timer.
- Once the timer is up, return to the TNT crate to collect the new stick and repeat the process.
This farming route is simple, as all the required components and the crafting station are within the same room.

Frequently Asked Questions (FAQ)
Why do my items keep falling through the map in Stage 2? This is a well-known physics bug in How to Make an Atomic Bomb in Your Garden. The floor's collision detection is unreliable for crafted or dropped items. The definitive solution is to perform all crafting on an elevated, static surface like the central workbench in the lab.
What is the exact recipe for an explosive plate? The recipe is one stick of TNT combined with one Water Barrel. No other items are required.
Can I use other explosives instead of TNT? No. The crafting recipe is specific to the red stick of TNT found in the laboratory. Grenades or other explosive items you may have will not work for this particular puzzle.
Where do I use the explosive plate? The plate is used on the large, reinforced steel door in the same laboratory where you craft it. Approach the door with the plate in your inventory, and an interaction prompt to place the charge should appear.
The Final Word
Success in making explosive plates hinges entirely on ignoring your instincts to craft on the spacious floor. The developers placed a stable, reliable workbench in the middle of the room for a reason. By using it as your designated crafting station, you neutralize the game's most infuriating bug and turn a potentially game-breaking obstacle into a simple, two-step process. Remember: workbench first, and the rest is easy.
