Traditional sparklers leave you with a hot piece of metal wire, which can easily burn you or other people. These new eco-sparkler sticks are made on bamboo which just burns away to ash. You still need to be VERY careful with them, of course. PLEASE FOLLOW THE INSTRUCTIONS ON THE PACKET. Don’t wave them about, and NEVER give a sparkler to a child under the age of 5.
The safest way of using these is to stick them in the ground rather than holding them.
