Explosions and goo – a science party!

Today heralded the middle chick’s birthday party. She and I decided, with the help of Pinterest, to have a mad scientist’s party. I am exhausted, but she reports that it was the best party ever, and her friends were all very excited by it all. The preparations involved a trip to Costco at midday on Saturday – a mistake I will NEVER make again. However this morning, a bizarre thing happened, and we were ready for the guests to arrive half an hour before the appointed time. This has never happened before! The difference this time? The three chicks helped. Yes – you read correctly. They helped! There was assistance galore from the two girls, and even a modicum of following instructions from the boy. It truly was miraculous!

The explosions I hear you ask?

I warned the little scientists that the nature of experiments meant that some might not work. The first experiment – making elephant toothpaste – was a bit of a fizzer. But not in the way that we expected. Instead of our mixture foaming up and out of the bottle, it slowly fizzed and rose over half an hours, then slowly subsided. A good lesson in not always succeeding! We used the instructions from Preschool Powol Packets but don’t be dissuaded by the fact that ours didn’t work – I was using 3% hydrogen peroxide and they recommended at least 6%.

Next we made time bombs – vinegar and water in a bag, then added baking soda in a folded piece of paper towel, sealed it and waited. We probably went a bit overboard on the papertowel so they took a while – but the suspense was delicious! And they DID explode!  We found the instructions at Geeks Raising Geeks .

To counteract the delayed gratification experiment, the next one involved instant effects. The ingredients? Diet Coke and Mentos. I read about this on a number of sites after the middle chick requested it. The main trick with this one is to get the original Mentos, and drop them in at the same time if possible. We made a paper tube and had a piece of paper that was pulled out to drop the Mentos in. On the first go we used 4 Mentos. Second time round we used 10. For the third bottle we used 14. Each time the eruption was larger with more Mentos. The kids loved it – smiles, amazement and delight!

Eruption number 2 (10 Mentos)

After a bit of refuelling with snacks the next experiment was making bouncy rubber balls. No photos unfortunately but they did enjoy the sticky-ness that turned into bouncing balls. Only a couple of failed experiments with this – the birthday girl and my boy – one had the mixture too dry and the other too wet! The recipe for these was from Mom to 2 Posh Lil Divas.

The final experiment? Making their own “Lava Lamps”. We found the instructions at SL Smith Photography. The ingredient that made them bubble was Alka Seltzer. I had planned to send them home with a tablet each to show their families but they had so much fun doing it at the party that the tablets were all used up. I suspect that any brand of fizzing or effervescent tablet would work. Again there was much oohing and aahing.

Lots of fun and only a bit exhausting for the hostess! Luckily my beautiful friend Ms C stayed to assist with the festivities – what a godsend! Although it went well I think it might be a while before I decide to host another party at home!

The rest of the week has been a return to our routine. I have been back at work and the chicks back at school. The boy has had a good week – the strategies that the school and I agreed on appear to have worked so far. With the good weather they have all been riding to and from school with Miss N supervising – it took a few days for them to settle down for her, but now they seem to have it sorted. I have enjoyed the return to my office and my team. It is busy, but having had my time to rest, I have been able to jump back in with energy.

I did manage a little bit of sewing still – the bag that I posted earlier in the week, plus a few little zipped pouches using laminated cotton for the outer. Then, thanks to the request for a pattern from the lovely Meredithe at Pomegranate and Chintz I decide to make another cross body bag but to photograph each step so that I can write a tutorial for it for you! The photos are done – now I need to sit down and write the instructions!

Hopefully later in the week……. However before that can happen I will need to buy a new keyboard – after the party one of the chicks helped themselves to some of the lemonade we had purchased for an experiment that wasn’t performed (inflating balloons by tipping ‘Nerds’ into soft drink) and spilt some on the keyboard. The result several hours later? A ‘d’ key and ‘k’ key that are sticking (I have spent most of this post backspacing after each word ending in ‘d’!!

I hope that you are all safe and well. There are terrible bushfires in New South Wales and more weather that will create difficulties for the fire fighters, so my prayers are with them all, and with those who have lost their homes already this week. It is a very early start to our fire season, so I am very grateful that my father did clean my gutters a couple of weeks ago! Thanks Dad!!

Be safe everyone.
