It would be nice if you mentioned somewhere in the instructable that this isn't actually the same thing as Silly Putty, which is a silicone-based product with somewhat different physical properties.

Well, now, that's just plain silly! ;0)

Silly Putty was fantastic because it could be molded, it could pick up inks from newsprint, and last & most importantly it could be shaped into a ball and it bounced rather well. Does this stuff bounce? If not, then it is NOT "Silly Putty" it is some other kind of generic "putty." Sorry, but all those qualities is what made Silly Putty, "Silly Putty." What can this putty do? What is its claim to fame? What is its claim to "Silly"?

This "silly putty" is listed in the category KIDS. Is something full of borax and glue suitable for kids?

This is GAK not silly putty!!!!! RAGEEEE!!!

I know! Here I was getting all excited that I'd be able to make some dilatant compound (http://www.dowcorning.com/applications/search/products/details.aspx?prod=01512137&type=PROD) but nooooo, just got a rather fantastic instructable that's extremely disappointing because the title is oh-so-wrong.

Was thinking the same thing.

Great ibble the pictures are amazing.

Interesting. So Borax can still be bought in the US? It has been banned from Europe. As a private person you are not allowed to buy it.

Here is what wikipedia says:

Borax was added to the Substance of Very High Concern (SVHC) candidate list on 16 December 2010. The SVHC candidate list is part of the EU Regulations on the Registration, Evaluation, Authorisation and Restriction of Chemicals 2006 (REACH), and the addition was based on the revised classification of Borax as toxic for reproduction category 1B under the CLP Regulations. Substances and mixtures imported into the EU which contain Borax are now required to be labelled with the warnings "May damage fertility" and "May damage the unborn child".

Classic over-reach by some government worker that read something somewhere. Borax is only a problem in two cases, ingesting large amounts over a 5+year period, and the typical considerations as an irritant when dealing with it in power form due to dust in the lungs. (or ANYTHING in power form for that matter) The FDA in the U.S. here does that with a lot of substances too, so you're not alone! It's a shame, it's really an amazing natural compound that can do many, many useful things for the DIYer. From fire-proofing, to preserving foods, to lowering the melting point of gold (rather than use mercury) BTW, lover your instructables!

added to the fact that many are lobbied by competition... tide, gain, etc ring the bell?

You may note that what you quoted does not say banned in any way, just required labelling laws, by the way.

You can still easily buy borax in the UK at least. You just do it online. No controls I could find (I needed it for taxidermy purposes). As far as I'm aware, the "ban" on borax is selling it as general purpose laundry aid. It can be sold as raw chemical (with the warning on it but who's going to be snorting a huge amount of borax?)

very good recipe, thanks!

what sort of glue?

any white casein glue; elmers is the name brand, but generic "school glue" is just the same.

amalkhan (author)  Stan1y9 months ago

White glue, like Elmers. Take a look at the second pic under Step 2, thats what the bottle looks like =)

CaroGow9 months ago
would this work with the borax substitute we can get in the UK?

Thanks for the easy recipe. The image says 1/4 cup borax instead of 2 tablespoon. It's a bit misguiding. I read through the rest of the steps that it was 2 tablespoons only.

Oops! Thanks for pointing that out. I just edited the image. =)
