Best cakes ever

My last birthday cake was pretty cool – it spells my name in morse code using maltesers and chocolate fingers.

When I was six my cake was a chocolate cake with the middle bit cut out and white icing in the shape of a dinosaur skeleton, then with the cake crumbs put back on top of it. We dug up the bones with spoons!  We can’t find the photo of that one, though.

I found this site that shows you how to make a cake that looks like Jupiter – even when you cut into it!

A day at Cambridge University Festival of Science

In the Pathology Department I made pathogens out of sweeties. The marshmallow with the shoelaces is salmonella and the other two are parasitic worms. You can see their faces.


We learned a dance that showed how haemoglobin gets oxygen from the lungs and takes it to the muscles.

In the Chemistry Department I played in the non-Newtonian slime, then extracted the DNA from a strawberry using washing up liquid, pineapple juice, ethanol and a tea strainer. The white goo in the last two pictures is the DNA.

Then we watched them make ice cream using liquid nitrogen.  It was really tasty!  I won a prize for the chemical elements quiz, played with Teflon-coated magic sand, and built a model hydrogen molecule.

In the Pharmacology Department I looked at water fleas through a microscope and we counted their heartbeats then gave them red bull to drink to see if their hearts would beat faster and then alcohol to see if it would beat slower. They let us catch one of them with a pipette, and take it home as a pet.

In the Psychology Department I was in an experiment about illusions and tried experiments about gambling and about how people make decisions.

Finally, we went to a pretend crime scene and did forensic science.

It was a really amazing day!
