Interesting idea. Encourage you to this apply LEAN principles to determine consumer acquisition and retention. Get into small based transactional testing via DTC marketing to assure you have product market fit prior to spending $100K+

Hi Dr. Goldstein. Thank you for your kind words and feedback. It is greatly appreciated. Your suggestion to apply LEAN principles and small-scale testing first before transiting into DTC marketing provides an excellent safety net that we can adopt to reduce financial risks.

Our original plan was to first conduct smaller focus groups and test market response via social media to garner feedback, interests and generate awareness for the brand and product before iteration and launch. Hence, your suggested strategy will certainly complement our endeavours.

Can water be run on the sticker without scrubbing to reveal the hidden sticker image? In tests, did any children get to the image without actually washing their hands?

Hi Ms. Sieffert. Thank you for your question.
Yes, without lathering, continuously running water on the surface would eventually dissolve all the soap layer. This would, however, take a very long time to achieve and waste an incredible amount of water. Children would then immediately start rubbing to accelerate the process. We want to ensure that there is no shortcut to reveal the reward.

We have not observed during our testings any of the children reveal the surprise without washing their hands.
