Ferro slime is a magnetic slime that we made by combining slime (recipe below) and Iron filings. First we tried iron oxide but when we put it in the slime and it magickly stopped working, we think this is because of the low concentration of the iron oxide in the slime, after this didn't work Oscar suggested to use iron filings witch work well, unfortunately we runout of time and couldn't continue.
Recipe:
Location: At the head of either table with gas taps for Bunsen burners
Materials/Equipment
The colours (preferably three of each in those small flaming colours bottles)
Strontium
Lithium
Zinc
Sodium
Calcium
Barium
Copper
Potassium
Equipment
5 heat proof mats
4 smaller heat proof mats
16 vaulves
8 tongs
8 spatulas
2 500ml water filled beakers
2 Bunsen burners
3 or more bottles of methylated sprites
1 bag of cotton balls
Method
get a cotton ball and put one in a vaulve
pour about 4 swirts of methylated sprites
get your choice of salt for your choice of colour and put two spatulas worth of the salt on the cotton ball
rub the salt around the cotton ball so you get colour in all places
pick up your salted and meth soaked cotton ball and wave it over the Bunsen burner to light it
enjoy the wonderful flames
when the fire starts to die/smoke or when you get bored quickly place it in your vaulve and put a lid on it
wait 2 - 3 minutes for the smoke to fully go away
then place the waste in the 500ml water filled becker
repeat steps 1 - 9 if you want another colour or to do it again
Science
different salts -> different electron configurations -> different levels heat energy gained -> different levels of light energy released -> different colours
when fire heats it makes the electron in the salt vibrate and make kinetic energy, they need to release this energy otherwise they are unstable and they do so by letting light energy go and since there is different salts with different electron configurations we get different colours

SECRET
This activity will be in the Biology Lab.
Our final idea for the microscope exhibition is that we'll have 3 micro-stations that all have slightly different functions. Each station is mainly based on exploration and new buskers are supervised but free experiment themselves. They are:
Prepared Compound Microscopes Micro-station: Selected prepared slides are on show with posters sharing a little bit about them.
Items under prepared microscopes:
Feathers
Human stomach cross-section
Paramecium
Other notes:
Exploration Compound Microscopes Micro-station: New buskers can make their own slides (under supervision) to examine.
Items under exploration compound microscopes:
Feathers
Pond water
Leaves/flowers
Other notes:
Water must be used when preparing slides
Exploration Binoculars/Dissection Microscopes Micro-station: New buskers can interact with larger objects.
Items under exploration binoculars/dissection microscopes:
Feathers
Leaves/flowers
General Equipment:
4 + Compound Microscopes
Box of prepared slides
Posters about prepared slides
Used slides + slide covers
Water (in beakers, none in Bio Lab)
4 + pipettes (1x paramecium, 1x pond water, 1x water, 1 spare)
2 + wooden/chopping board
2 + scalpel or sharp knife
2 + Binoculars/Dissection Microscopes
2 + Lights
Scissors
Pack up equipment:
Trays (to put slides in)
Paper towels (for slides)
Items under observation (that need collection):
Feathers (chicken, mallard etc.)
Flowers (lavender etc.)
Leaves (apple/pear leaves, etc)
Pond Water
Other notes:
Liquid (we'll use water) must be used under the coverslip
Use a mix of compound microscopes and dissection microscopes (binoculars)
This little animal we found in the paramecium culture really doesn't like the heat generated by the light on the microscopes (and I've already forgotten it's name, although I'm pretty sure I found the exoskeleton of a similar looking creature (but bigger) at Duck Pond Nu.3)
Location: Anywhere near a gas tap in a lab.
Materials/ Equiptment:
4L Water
65ml Dish Detergent
45ml Glycerol
Matches
5+ splints
1x big tray/bucket
1x Stiring rod
2x 100ml beaker
1x 1L measuring cylander
1x heatproof mat
1x long gas tube,
1x hand towel
Caution (Essential)
Method
Fill the 1L measuring cylander to the L mark, then pour into bucket
Repeat step one (Once)
Pour in both glycerol and dish soap
stir well with stirring rod
Fill the 1L measuring cylander to the L mark, then pour into bucket again
Repeat step 5 once (You should now have 4L of water
Mix solution once again (Thoroughly) That is the solution ready
Get person who is lighting their hands on fire to take anything off their wrists and pull lab coats back,
Get person who is lighting their hands on fire to rinse their hands
put the long gas tube into the bucket and open the gas valve
When sufficent bubbles, turn off the gas
Get person who is lighting their hands on fire to take a medium- small ( In other words NOT LARGE) scoop with one had
Wipe the bottom of the persons hand thoroughly (DOUBLE CHECK IT IS NOT A LARGE SCOOP)(you might get burnt if so)
Light match, light splint with match
Tap the bubbles slightly with the burning splint, it should light on fire.
Science: (Waiting on Hector sorry I don't know well)
Middle Bench somewhere towards the back near the big sinks.
Equipment:
All big measuring cylinders.
Elephants Toothpaste Tub
Hydrogen Peroxide
Dishwashing Liquid
Potassium Iodide
(Note:I will be briefing Newbies so could someone please just have this ready to go)
Setup:
Measuring Cylinder in the tub
Chemicals to the side.
Mehod:
Enough Dishwashing Liquid to cover bottom.
100 ish ml of hydrogen peroxide
3 pipettes of KI
Put the KI in Measuring Cylinder
Speech:
The hydrogen peroxide is breaking apart into water and oxygen, which is a slow process that is happening all the time, so we add potassium iodide which is a catalyst ( a chemical that speeds up a reaction) The dishwashing liquid catches the oxygen from the reaction and that's why it foams. The steam is because it is what is called an exothermic reaction, meaning it produces heat, so the reaction is at least 100 degrees cause water boils at 100 degrees.
Things needed:
Teabags
Matches
Heatproof surface
Method:
Empty teabags and remove strings
Stand teabags upright on top of a heatproof surface
Set fire to the top
Watch the tea bag fly up
