Experimental electronic petal dropping prop

A project inspired by a friend in the theatre industry who was asking about the technicalities of creating a prop rose in a glass bell jar where the petals fall off in a controlled manner during the performance.

My initial thoughts were a magnetic system or an assembly with boden style tubes to allow pins to be pulled to drop the petals, but then I decided to experiment with resistors and wax.

This video is a good demonstration of how changing materials (higher temp wax and lighter petals) can change the results completely.

The prop as shown is just a prototype. It would look more rose-like with more petals and a smaller connection hub.

If you enjoy these videos you can help support the channel with a dollar for coffee, cookies and random gadgets for disassembly at:-

This also keeps the channel independent of YouTube's advertising algorithms allowing it to be a bit more dangerous and naughty.
