Bath bomb makers face a constant challenge: you invest time weighing citric acid and baking soda, carefully packing your moulds, only to discover 48 hours later that your fizzy sinks instead of floats, or dissolves in 15 seconds when you planned for 60.
Big Bass Blast eliminates that guesswork by simulating the physical behavior of your bath bomb before you press it. Enter your mould dimensions, cavity count, and dry weight, and the app predicts fizz duration, float probability, hardness after curing, tub ring intensity, and roaming behavior in the water.
The community workspace allows you to save drafts on your Bench, move active batches to your Press Tray with live progress rings, and track curing items on your Shelf with countdown timers. When something goes wrong, log the fault with photos and notes so you can troubleshoot with other makers or refine your process next time.
Adjust cavity count or mould size and watch total batch weight recalculate instantly. The app shows you dry ingredient mass, gas volume, and cost per cavity in real time.
See projected fizz seconds before you press. The app analyzes your mould shape and dry weight to estimate how long your bath bomb will actively dissolve in water.
Browse hemisphere, fluted dome, ring, and tube templates with exact millimeter dimensions and cubic centimeter volumes. Select any mould and the app auto-fills your recipe card.
Know whether your bath bomb will float or sink based on mould geometry and pack density. The app flags float-friendly shapes and warns you when a design is too heavy.
Six circular gauges display fizz vapor, fizz seconds, hardness, float status, tub ring intensity, and roaming distance. Each wheel updates as you tweak your formula.
Move finished items to your Shelf and watch the countdown ring drain as your bath bombs harden. Set custom cure windows and receive notifications when items are ready.
Big Bass Blast is maintained by a team of crafters who experienced the same frustration: wasted ingredients from unpredictable results. The app uses physics-based models to estimate bath bomb behavior, and the community archive is curated by volunteer moderators who test and verify each shared recipe.
