Subject: [DCHAS-L] "safe" barking dog demo

 

Just a quick yes or no, please.  Would you lump the "Safe Barking Dog Demo" in the same category as the Rainbow Demo & Tornado Demo (i.e., it is an open flame demo, where additional flammable fuel -- let's say 95% ethanol -- could be added to an already confined ignited situation, therefore it is not prudent to perform, especially at a local grade school).  We are having a discussion about it.

 

Here are two links that show/explain it:

Thanks.
