Abstract

A visual effect device for producing the effect of falling snow/ash, the device including a holder containing a sublimable solid for heating, a powered heater for controllably heating the sublimable solid to a particular temperature and a connector for supplying power to the heater. The sublimable solid may be metaldehyde or hexamethylenetetramine. Also disclosed is a method for generating the visual effect.

Claims (26)

Claims
1. A visual effect device for generating a floating particulate visual effect, the device comprising: a holder containing a sublimable solid, a powered heater for heating the sublimable solid to a temperature in a predetermined range of 80°C to 450°C, and a connector for supplying power to the heater.
2. A device as claimed in claim 1, whereby, in use, the sublimable solid sublimes.
3. A device as claimed in either claim 1 or claim 2, wherein the device is for generating a snow/ash visual effect, preferably a falling snow/ash visual effect.
4. A device as claimed in any one of the preceding claims, wherein the device is arranged so that the sublimable solid may be pressed against a heated surface of the heater during heating.
5. A device as claimed in claim 4, wherein the device is arranged so that the holder may be pressed against a heated surface of the heater during heating.
6. A device as claimed in claim 4 or claim 5, wherein holder and/or sublimable solid may be pressed against the heated surface of the heater by a pressing mechanism.
7. A device as claimed in claim 6, wherein the pressing mechanism comprises a weight, a motor or a resilient mechanism.
8. A device as claimed in claim 7, wherein the resilient mechanism comprises a spring, optionally a leaf spring.
9. A device as claimed in any one of the preceding claims, further comprising a casing.
10. A device as claimed in any one of the preceding claims, further comprising a gas inlet for flowing gas over the sublimable solid, in use.
11. A device as claimed in claim 10, wherein the powered heater comprises a hot gas blower for supplying heated gas to the gas inlet, preferably a controllable hot gas blower to supply gas at a controllable temperature and/or controllable flow rate.
12. A device as claimed in either claim 10 or claim 11, further comprising a fan for supplying gas to the gas inlet, preferably a controllable fan to supply gas at a controllable flow rate.
13. A device as claimed in any one of the preceding claims, wherein the powered heater is an electrical heater and preferably wherein the connector is for supplying electrical power to the heater.
14. A device as claimed in any one of the preceding claims, wherein the heater comprises at least one hotplate.
15. A device as claimed in any one of the preceding claims, wherein the predetermined temperature range is 105°C to 350°C, preferably 120°C to 320°C, more preferably 130°C to 300°C, most preferably 140°C to 290°C.
16. A device as claimed in any one of the preceding claims , wherein the sublimable solid comprises one or more shaped blocks.
17. A device as claimed in claim 16, wherein the shaped block is in the shape of a pellet, a block with one or more peripheral cut-outs and/or a block with one or more holes.
18. A device as claimed in any one of the preceding claims, wherein the sublimable solid comprises metaldehyde, hexamethylenetetramme, other sublimable compositions and/or a mixture thereof.
19. A device as claimed in any one of the preceding claims, further comprising one or more fixings to fix a lanyard to the device.
20. A device as claimed in any one of the preceding claims, wherein the device is substantially portable, preferably hand portable.
21. A device as claimed in any one of the preceding claims, wherein the sublimable solid is in the form of one or more pellets comprising the sublimable solid.
22. A device as claimed in claim 21, wherein the or each pellet further comprises a binder, optionally wherein the binder comprises polyvinyl actetate and/or water.
23. A method for generating a floating particulate visual effect, the method comprising, providing a device as claimed in any one of the preceding claims, providing a sublimable solid contained in the holder of the device, and supplying power to the heater thereby heating the sublimable solid to a temperature in the predetermined range and causing sublimation of the sublimable solid.
24. A method as claimed in claim 23, the method further comprising pressing the sublimable solid and/or holder against a heated surface of the heater during heating of the sublimable solid.
25. A method as claimed in either claim 23 or claim 24, wherein the method further comprises flowing gas so that it passes over the sublimable solid.
26. A method as claimed in claim 25, wherein the device comprises a gas inlet for the supply of flowing gas.
