We were very satisfied with the 2x3 Flash Paper. We used it during a special activity at a church
retreat for our teenagers. They privately write names on the paper that they've been called that
were hurtful to them, then they place them in a heat-proof clear glass bowl. When ignited they flame
up & disappear, leaving no trace. It's a dramatic effect and one they talk about and remember for a
long time! (Note - the papers are damp & must be spread out to dry a day in advance to be able to
write on them.)
