Common groceries plastic bag… I tried with paper tissue, not vibrating enough. Didn’t really experimented yet with various plastic tensions but I guess tighter would require higher acoustic energy for same visual effect.
Yeah mirrors usually don’t attenuate laser power significantly… but can change power density (laser spot size at given distance) if mirror is not flat: beam gets focused too much and that can be a hazard. Just keep laser power under 5 mW at home and no burning anywhere! Wear adapted goggles. Be safe!
beautiful work. has both artistic and scientific beauty. thanks for sharing. keep posting more such...
Thank you! Working on interference patterns with more powerful laser beams now, hopefully I’ll get something cool soon.
@@Fellouche thanks for response. Will await your next post. Btw, whats the plastic membrane used on speaker ... curious

Wow, amazing work.
Glad you like it! Thanks.
This is amazing
Interesting
Instructions not clear; I burned a hole in my wall with my Wicked Lasers 2 watt laser. 🤷♂
