Stroboskop by Klasek Fireworks.

This is a pack of 64 miniature strobes. They are great fun and can be used practically anywhere outside.

Once lit a brief shower of sparks turns into very strong bright strobes of light coupled with an eerie intermittent whooshing noise. The coverage of the light from something so small is truly amazing!
