Volcano for Vinegar - Soda experiement

thingiverse

A Fresh Remix of the Smiling Volcano with a 150ml Inner Pocket for My Kid's Presentation on Volcanoes! This allows for 125ml of vinegar to be poured on top of 30ml sodium bicarbonate. V2 adds a 6mm hole for air to flow out while pouring. The Funnel is the Same Size as the Internal Chamber, Holding Almost All the Liquid and Perfect for Discussion. The Spout is 2mm Smaller than the Volcano, Fitting Nicely and Still Large Enough for a Good Flow. I Would Highly Recommend Washing Quickly, as I'm Not Sure of the Long-Term Effects of Vinegar on PLA. We Did Our First Tests This Morning, Finding Out That a Little Less Liquid Gives a Smoother Volcano. Here Are the Ingredients: Place in the volcano: - 1 Full Tablespoon of Sodium Bicarbonate (Baking Soda) Mix Together and Then Pour into the Volcano - 40ml Water - 4-5 Drops of Liquid Soap - 4-5 Drops of Food Colorant While Pouring the Water, Make Sure to Wash Away Any Remaining Soda from the Funnel. You Don't Want the Reaction to Happen in the Funnel. Pour in the Vinegar Smoothly but Not Too Slowly, Taking About 1-2 Seconds. Remove the Funnel Immediately but Smoothly. The Reaction Will Start in 2-3 Seconds and Last 5-10 Seconds. Ingredients: - 40ml Vinegar Using 40ml of Each Liquid Gives a Smooth Volcano, While 60ml Makes it Go Faster But is Less Interesting in My Opinion. Try It Out Yourself!
