Immiscible glitterable bottleable

What: a (well-sealed) bottle that shakes up and separates out

How: You need a leftover plastic soft drink or sports drink type bottle, around the 600ml size-ish makes for good handling, with a lid that can be glued shut. (This isn’t, strictly speaking, necessary… oh, who am I kidding. Glue or tape that f@!#!@ker down good and tight once you’re done.) Fill about a quarter of the bottle with oil, add a capful of food colouring, a guinea pig’s fart’s worth of loose glitter (I don’t know how much that is exactly, but I’m told quite sincerely it’s correct), and then top up with water leaving a small airspace at the top.

Mostly separated pre-shaking. The glitter usually collects at the base of the oil, but some always sticks to the bottle sides.

This was a baby toy I made for Kid 1 after seeing something similar at an open playgroup-in-the-park in Darwin. The idea is that they can shake it up, roll it around, try and crawl towards it or grab it, fiddle with the textures on the bottle (if your bottle has textures), all depending on age. And, of course, they can watch what happens as the oil and water mix and then separate out again. I found that the glitter tends to stay in the oil, and the colouring stays in the water. I suspect it might be possible to get oil-based colourings that would colour the oil as well so you’d have two quite different colours. I just used craft glitter, but if you were concerned about it being swallowed then edible glitter’s available at cake stores and should work fine for this too. I’ve never bothered trying to explain the oil and water thing to the kids, to me this is just a foundational activity, the sort of thing the kids add to their memory banks of “how the world works” that later on they can pull out and say “Oh, is *that* what that was about”. Such as when a grandparent says knowingly “Like oil and water, dearie” and the kids are all “Like what now?”.

Extras: Really, there’s not a lot more to this, it’s pretty much what it says on the box (but maybe with less syllables than I like to use). There is one modification I’ve seen that could be useful though – using the bottle as a timer. Go to your room, and you can come back out when the bottle’s cleared again. Gives them something to watch, and a known amount of time to spend calming down or getting themselves together or just getting over it (whatever “it” is). My bottle only takes a minute or so to clear, but I think there are recipes online using glitter glue that separate out a little more slowly so you can tweak the timing.

Origami baby ball

What: a lightweight origami toy/gift for a little baby.

Four month old, fascinated by something they can actually grab and hold and turn.

How: To be honest, I don’t remember exactly how or where we found the instructions for this, it was a random origami book somewhere, but I’ll bet it’s available on YouTube nowadays. The idea was that you folded six of these shapes, attached them together as a cube, and they flexed into a ball shape. The only trick was attaching the bits together. I think I used stickytape for this one, because I didn’t want to risk staples flying around when the baby grabbed with both hands and yanked in opposite directions. The first time I made one of these, for my first Kid 0, I used paper glue (just a standard glue stick) and that worked OK until they worked out how to apply more force than the glue resists. So, fastener is your choice, see what works for you and your kid’s developmental stage / attitude towards interesting objects. I found there was a huge difference between 3 months, 4 months, 6 months – and between children of the same age (there are smashers and kissers and many types between).

I loved this ball because it was light weight, so the baby could pick it up, wave it around and then when their hand strength predictably yet unexpectedly failed they could drop it on their face – and this wasn’t a problem. I also liked that it had lots of pointy-out bits – paper, not stiff, so they didn’t hurt or poke, but small grasping fingers could find plenty of bits to latch onto in order to try and grip. That made it suitable for a whole range of manipulative abilities, it wasn’t something they just accidentally knocked around the room because they couldn’t grasp it when they threw their arms in its direction. Because it was home made we could use a range of textures and colours and patterns in the paper, getting more subtleties than baby toys often have. It’s also visually interesting, with the combination of detail and symmetry. And it’s paper, so if they chew on it, well, it gets soggy and maybe it tears, but at the end of the day it’s still only paper. You can make another one easily enough.

Extras: The first one of these was made as part of an origami party for Kid 0, when friends of ours came over and made lots of origami shapes for a mobile. So it was a nice social thing. It was actually made by a Kid 11, from memory, who really enjoyed working through the printed instructions and then repeating the steps five times to get the six identical pieces. I think you’d need at least a Kid 8 or 9 to make it – it wasn’t too tricky, but it did take a little folding precision (plus of course the ability to read and follow instructions!). I made the one in the photo here, and I also made a third one that we mailed to a friend for a new baby gift. Lightweight = cheap postage!  These latter two were both made under Kid 1 and 2’s “supervision” – they helped select the pieces of paper I used and which order they attached in.
