Welcome to the forum. There are too many easy choices. Just be safe and keep the laser away from children. Shiny/reflective surfaces will cause an eye injury very easily.
It's a bad idea to use a laser. Unintentional blinding potential from unforseen circumstances. Lasers are only safe when all precautions are taken. Too many variables.
If you want to do it safely, use a hobby rocket igniter on a long twisted pair of wires. Toggle your switch and light the fire. Pull your igniter out with the wires before it goes up in flames.
Remember though, we are scientists. Cold calculating scientists. We don't do this for fun. :D
