Re: Light-bums

Dear Bandit,

I pointed out to Littles a curious effect of intersecting curves of light in a cup. I call this the "light-bum" because, let's be honest, what else does it look like? Photo enclosed.


 


 I actually think it looks a bit better in the bottom of an empty cup, but it's easier to
photograph if the cup is full.         

I think Bluey and Bingo would really appreciate this one. But instead of just showing it to them, maybe you could make it a challenge: can you find a bum made of light? Offer a ridiculous prize like horsey-rides on demand for a week. I'm sure they'll get it. It'll take them the better part of 8 minutes, I imagine.

And for bonus points... DOUBLE LIGHT-BUM IN THE BATH!

       

I have since learned that the proper name for this phenomenon is a "caustic curve", and now that I know that, I feel entitled to change my name to Sciency McScienceface.

Give my love to Chilli and the girls,

Best wishes,



Alastair.

Re: Daisies

Bandit Heeler Brisbane Queensland  Australia Dear Bandit, I enjoyed reading your letter about taking the children to the creek. It got me thinking about the many ways kids can enjoy nature. Littles and I have recently been making daisy chains. Incidentally, did you know that the word daisy comes from "Day's eye", because it opens in the sun? I think that's pretty cool. Chloe's dad told me that one. Anyway, to make a daisy chain, pick a daisy, and pinch a little hole in the end of the stalk. This may be easier to do with fingernails than claws, but do your best. If you accidentally nip it all the way through, you can nip the end off and start again as long as you don't run out of daisy (so it pays to pick one with a long stalk to begin with!) Push the stalk of the next daisy all the way through, and repeat. Then when you think it's long enough, make a big hole in the last stalk, and push the first head through to make the whole thing into a loop. Littles in...

Re: Independence

Bandit Heeler Brisbane Queensland  Australia Dear Bandit, Littles has a new favourite word: "Independent." Its main use seems to be when the clock is racing towards 9am and we are desperately trying to get her dressed. It means we may not help her in any way whatsoever, no matter how much time it would save. Independence is wonderful, but not if it means giving up accepting help. Being an independent person may be, in some ways, similar to being an independent country. I have the misfortune of living in a country that opted, eight years ago, not to be an independent country. It was, at that time, insufficiently grown-up, like when we tried to toilet train Littles and it didn't work because she wasn't ready. We who want independence for Scotland are trying to have the question asked again, but opponents maintain that the answer of eight years ago should stand today. No! We don't want to toilet train! We are proud of our nappies, thank you very much, and are staying...

Re: Bodies

Bandit Heeler Brisbane Queensland  Australia Dear Bandit, I loved reading your letter about exercise. We don't get enough of it with small crazy people running around us, that's for sure! Most of my exercise consists of carrying Littles here and there on my shoulders - the "Good seat", she calls it. And, Bandit, that used to be easier! She's getting taller and I'm getting shorter. You're very right that it is important to exercise to stay healthy, but I'm not sure it's healthy to be worrying about your weight. In fact, I'm pretty sure that's an unhealthy attitude, especially when we show it in front of our kids. My advice would be to throw those scales away! They're not helping anyone. So if you're exercising because you want to be fit and healthy, good on you. But if it's because society is telling you that you're not an attractive shape, then society can just bugger off! I'm actually a bit worried about raising a daugh...
