We love Nerf and their latest release is the Laser Ops Pro range. Brand new laser battling blasters which bring Nerf, Laser Tag and augmented reality together in a brand new and very different type of battle to any other Nerf we've ever played with... and it's really rather fun.


In the box are 2 x Nerf Laser Ops Pro blasters and 2 x rubbery armbands to hold smartphones - which are optional. You will need 8 x AA batteries - 4 for each blaster. The packaging is great. Plastic-free and you have storage for your set afterwards to keep it all safe.

We can't see lots of things, including a lot of gasses, but we can prove that they are there. We can create Carbon Dioxide gas very easily, and because it is heavier than air, we can use it for a trick...



EQUIPMENT:
1 candle - a tealight is perfect
1 bowl with about 1cm water in the bottom
A small jug, mug or beaker.
1 teaspoon bicarbonate of soda
2 big glugs of vinegar (about 1oz)
Cling Film

Lat weekend we were guests of CBBC and Croxteth Hall And Country Park for the CBBC Summer Social. The weather was on our side, dry and not super hot, and unusually gates opened at 9.30am, so we set off bright and early, in time to take a few photos before the crowds really descended.


The CBBC Summer Social is a festival for families with children aged around 0-11, and loads of children's TV favourites were there. It was lovely to find the whole site is really flat and relatively compact, especially when you consider what they managed to fit in!

Cavemen probably played with miniature catapults as children, the technology is incredibly old. They are very simple to make and this is one of the simplest. It is a great way to use energy and motion to create different types of energy and motion. Mechanics, powered by your finger...



EQUIPMENT:
Small collectible toys, rubber are best*. The type that come in blind bags and don't cost more than 50p each - then your mum won't be mad you won't be sad if you do temporarily lose any (don't use your favourites).
Dessert or soup spoon
Plastic water bottle, half full of water with the lid on tightly or cardboard tubes (kitchen roll or crisp tubes).
Sticky tape
Plastic bowls or similar for targets

*Small objects to fling - if you don't have any small collectible toys or yours are too precious to risk losing, you can use tightly crunched up paper. There are other rules:
a. Your objects cannot be metal or glass, or feel heavy or hard like metal or glass - e.g. dice.
b. Your objects cannot have sharp edges, points or corners.
c. Never aim towards animals or people, and watch out for your cat/baby brother getting into the way.
d. Your objects must not be bigger than the spoon, if they overlap the edges, they're too big.

It's about time I updated you on what Gary is up to, although it is with a degree of disappointment that I inform you he still doesn't have a 3-storey cat hotel, but you never know, one may just be in his near future... Black Friday is only getting closer...


For anyone who has missed Gary's story, he arrived, he squealed (for an hour). We let him in, he repaid us in hugs and a terror of the outdoors, followed by a persistent inability to have a wee. The internet raised some of the money, the vet took a hatchet to Gary's credentials and he's been just fine since.

He's only 3 and he's had the most adventures of any animal I've ever had.


Gary is the only cat I have ever actually tolerated liked. I'm not a natural cat person, I like dogs - but don't tell Gary. He's very excited by passing dogs, but I don't think he intends to befriend them.

The Butterfly Effect suggests that when a butterfly flaps its wings in the Amazon jungle, the ripples around the world might cause a roof to blow off in China, an apple to fall from a tree in the UK, or a Russian woman's hat might blow away. We see the butterflies' wings flap, but we can't see the waves of pressure it causes. In this activity we can hear them though...


EQUIPMENT:
A sheet of A4 paper

World Calligraphy Day isn't just about showing off your calligraphy skills (thankfully because mine are very limited!), it's about getting everyone writing. Manuscript Pen Company have partnered with Birmingham Children’s Hospital and created the ‘Say Something Special’ campaign.


The campaign is encouraging as many people as possible to write a special letter to the children in  Birmingham Children's Hospital. These can be sent to: Say Something Special c/o Small Man Media, 2nd Floor, 6 Waterloo Road, Wolverhampton, WV1 4BL. All of the letters will be forwarded on to Birmingham Children’s Hospital alongside some Manuscript products for the hospital to use for their art classes and play sessions.

Today's 5 minute activity is one of the very simplest, but most effective. Our bodies and brains are incredibly complicated and clever, and most of the time they work together really well, but it is possible to confuse our brains and make it appear that something isn't what it seems.


EQUIPMENT:
Your hands
1 bowl cold water - from the cold tap
1 bowl lukewarm water - 2/3 cold and 1/3 hot
1 bowl warm water - comfortably warm and toasty

Science can't explain everything, but sometimes it has a very simple explanation for something that seems impossible. If you hit yeast extract (Marmite, Vegemite etc) it appears to change colour from very dark brown to very light tan colour, almost from black to white. But why?


EQUIPMENT:
1 level teaspoon Yeast Extract - Marmite, Vegemite etc.
A spoon, fish slice or other utensil to hit the yeast extract with.
A plastic plate or shallow bowl - not a Melamine camping plate, it'll break. The softer sort of plastic.

Here's something for the engineers of the future to get their teeth into. You can make a hole in more than one way, and if you do it carefully, you can even walk through a hole in a postcard...

This activity is quite hard because it requires concentration and careful cutting. Younger scientists may need older assistance, and there is always sticky tape!


EQUIPMENT:
A postcard sized piece of thin cardboard. A postcard is perfect, cereal box is great.
Scissors
A light coloured, thin felt tip or a pencil or wax crayon
A thick marker or felt tip in a dark colour.
