I picked one of these up in the toy section of Debenhams in Mahon pt in Cork last year for 5 Euro (a smaller version admittedly, but 'twas a great deal!).
Dunno if they still have them, but it's worth a try!
Very impressive...so in physics there is no way for light to reflect off of light...say laser light being condensed and uniform photons, more energetic wave length...being struck by a less energetic light source albeit a laser there would be no results "reflection"?...thinking particle/wave qualities if i cast a stone in a pond then a second in a new location there is a new wave created in a new direction...less there is cancelation...see my point?
Yes you do have a point; you can indeed get interference between two light sources, it's just not likely to be a factor in explaining the phenonema above. Interence would be most noticeable if both sources were single wavelength (like from a laser as you suggest) but in this case normal sunlight or flashlight incorporates many different wavelengths.
yes. I wasnt refering to the pig example. I was thinking more on photonic physics possibilities. Interesting so light can cause interference with other light if both sources were single wavelengths...Where would I begin to look if I wanted to put together an equation explaining or that already explains what would happen in light on light interference where single wavelength sources are involved?
Nope, turns out the light isn't being reflected off of the image, there must be some other explanation (this took me a while too so no easy answers). :)
is some of the flash light "light" scattering into the base concave mirror where the pig sits...and through refraction appearing fom the observer's point of view to be reflecting off the REAL image?
Why is everyone so interested in the pig??? This makes no sense!

Hi Enda,
I'm pretty sure Lennox do them. give them a call at 01 4552201.
If no joy get back to me.

Hi noel,
Any idea if you can get these in Ireland? Unfortunately they wont give me a credit card yet!!

so why can light reflect off a real image? Light reflects light?

Bingo! Impressive isn't it?
btw it's reflection rather than refraction above (sorry, just the teacher in me :) ).
Remember you can purchase these from teachersourcedotcom. It makes a great present.
