These bottles are amazing and lots of fun. I remember as a child I was always fascinated with them and could never work out their secret (and I'm not telling now either) and I remember I would be quite envious of my sister who owned a set for her dolls.

The idea behind these is a simple one. One bottle contains orange juice, another one milk. At first glance they appear full but when you put them to your dolly's mouth and tip them up, the liquid magically disappears! Almost as though dolly was drinking the contents! Amazing!

Of course there is an explanation for this that is actually quite unamazing and the whole thing is really just an illusion (I am afraid to tell you that dolly doesn't actually drink the contents ~ I know, shocker isn't it?) but like I said earlier, I still refuse to tell!

What is good about these is that they are extremely well made and very hard-wearing and durable so even if they get flung about, it is unlikely that they will break. And they are cheap. Our set cost us somewhere around £2.50-£2.99 I believe.

I have heard stories about the liquid inside evaporating or solidifying but this must only happen if the bottles are damaged or cracked as, three years in to owning these, ours still work perfectly fine and my daughter loves using them to feed her dollies, toy dogs, cuddly kitten, monkey etc etc etc I could go on.....

These are a great little toy, as I have already said, and a great accompaniment for your existing dolls accessories that are available from a wide range of stockists including Amazon of course who seems to sell everything nowadays! Prices can vary though you should not be expecting to pay anything over £3 or £4 at the most!

And the secret.......well, I am afraid unless you google it, that will have to remain a secret because I still won't tell.....
