Well...... there are a few solutions:
1) Use it as an ingredient for baking/cooking. A ton of recipes here.
2) Recarbonate the flat soda and drink it?! Yes, really. YOU CAN RECARBONATE IT!!! ( You can even make your own soda. I'll share a post about it soon.) Meantime, read this to find out how.
3) Recarbonate the flat soda and use as a science aid............ for the infamous Coke-Mentos experiment!
And that my friends is exactly what I did with the leftover flat Coca-Cola - the infamous Coke-Mentos experiment!
First of all, I added some flat Tesco Choice Sarsi (it was only RM 0.40 so how can I not buy it?). Then I added about 1/4 tsp of yeast into the bottle and left it to 'ferment' for 2 days.
Even without adding the Mentos, it was already bubbling.
Okay, on to the experiment.
