The method is depressingly localized to the creator's nearby shopping experience. It requires exact
duplication of the materials used, and alternatives (that you might find at your local grocery
stores) are not suitable.
I've spent considerable effort and money to find the exact
materials used in the instruction. Around $40 of testing out materials later, the effect is - at
best - a side effect of the materials themselves.
Was caught out 4 out of 6 performances
using materials as close to the description offered, simply due to the nature of the materials
giving the effect away.
I do not recommend this product.
