Lots of unique immersive experiences. Available anytime from your smartphone or tablet. Designed to make screen time productive and meaningful.

Foam Jack-O’-Lantern

What You Will Need

- hy­dro­gen per­ox­ide, H₂O₂ (any strength will do, but the less con­cen­trat­ed it is, the less dense your foam will be) (1/4 cup or 60 mL)

- wa­ter (1/8 cup or 30 mL)

- yeast (1/2 oz or 14 g)

- any food col­or­ing (1 tsp or 5 mL)

- liq­uid dish soap (1 Tbsp or 15 mL)

- 3 cups or small bowls

- jack-o’-lantern (you won’t need can­dles, but keep the top – it will serve as a lid)

Instructions

1. In the first cup, mix the hy­dro­gen per­ox­ide, liq­uid soap, and food col­or­ing

2. In the sec­ond cup, mix the yeast with some wa­ter

3. Put the emp­ty third cup into the pump­kin and pour in the con­tents of the oth­er two cups: first the soap so­lu­tion, then the yeast mix­ture

4. Quick­ly put the lid on the pump­kin: this re­ac­tion will pro­duce a lot of foam.

When hy­dro­gen per­ox­ide de­com­pos­es, it pro­duces oxy­gen and wa­ter. Nor­mal­ly this is a rel­a­tive­ly slow process, but yeast speeds it up dra­mat­i­cal­ly. The rapid­ly-gen­er­at­ed oxy­gen whips the liq­uid soap into a thick, vo­lu­mi­nous foam. There’s so much foam that it forces its way out of the jack-o’-lantern!

Jack-O’-Lantern in Green Flame

What You Will Need

- cop­per(II) chlo­ride di­hy­drate, Cu­Cl2 (1/2 oz or 15 g)

- ethanol, C2H5OH (96%) (1 cup or 240 mL)

- toi­let pa­per (or dry nap­kins)

- lighter- spray bot­tle- jack-o’-lantern

Instructions

1. Mix the salt crys­tals with the al­co­hol (the salt will par­tial­ly dis­solve, cre­at­ing a green­ish so­lu­tion);

2. In­sert the roll of toi­let pa­per or crum­pled dry nap­kins into the pump­kin, then thor­ough­ly wet with so­lu­tion;

3. Spray the pump­kin from all sides with the al­co­hol so­lu­tion – this will make the ex­per­i­ment much more im­pres­sive.

When ig­nit­ed, the al­co­hol burns green. Why is this? The green tint is the re­sult of the cop­per ions from the salt. When heat­ed, they ab­sorb en­er­gy from the flame and lat­er re­lease this “ex­tra” en­er­gy as green light. Con­duct this ex­per­i­ment out­side and don’t leave your pump­kin unat­tend­ed.

Ob­serve fire safe­ty pre­cau­tions when con­duct­ing this ex­per­i­ment!

Smok­ing Jack-O’-Lantern

What You Will Need

- glyc­erin, C₃H₅(OH)₃ (1 tsp or 5 mL)

- 3 small can­dles

- 1 alu­minum can

- scis­sors

- pipette (to trans­fer glyc­erin)

- jack-o’-lantern (be sure to save the top—it will serve as a lid!)

Instructions

1. Set a few can­dles in the pump­kin and light them;

2. Cut an alu­minum can to make a stand as shown in the video;

3. Drip some glyc­erin into the hol­low of the can;

4. Place the lid (saved from when you carved your pump­kin) on your jack-o’-lantern.

Why does the glyc­erin va­por ap­pear? The can­dles warm the alu­minum, and the glyc­erin be­gins to va­por­ize in the heat, turn­ing into white, smoky clouds. This makes for a tru­ly ter­ri­fy­ing pump­kin – it’s both glow­ing from the can­dles and re­leas­ing omi­nous smoke from its eyes and mouth!

Zombie-chicken eggs

What You Will Need

- eggs

- red cab­bage

- salt- pep­per

- bowl

- fry­ing pan

- stove

Instructions

1. Dice some red cab­bage and trans­fer to a 1L beaker.

2. Im­merse in hot wa­ter and let cool.

3. Fil­ter the mix­ture.

4. Break and sep­a­rate a few eggs.

5. Add the red cab­bage juice to the egg whites. The egg whites turn bluish-green.

6. Pour the mix­ture into a pre­heat­ed fry­ing pan and add salt and pep­per to taste.

The fried eggs turn out green, but smell and taste quite good! Aque­ous so­lu­tions can be neu­tral, al­ka­line, or acidic. Red cab­bage juice has an in­ter­est­ing fea­ture – it con­tains an­tho­cyanins, which change col­or de­pend­ing on the acid­i­ty of their medi­um. Ini­tial­ly, in a neu­tral medi­um, cab­bage juice has a pur­ple-crim­son col­or. When the cab­bage juice is added to the bowl of egg whites, the mix­ture turns green, as egg whites are an al­ka­line medi­um. The pH re­mains un­changed dur­ing the cook­ing process, and the eggs stay green.

Flu­o­res­cent Jack-O’-Lantern

What You Will Need

- ethanol (40%) (1/6 cup or 40 mL);

- flu­o­res­cent high­lighter (you’ll need its car­tridge);

- cup

- paint­brush

- spray bot­tle

- black­light

- jack-o’-lantern or pump­kin

Instructions

1. Re­move the car­tridge from the high­lighter and rinse it thor­ough­ly in al­co­hol to ex­tract its dye;

2. Use the paint­brush to ap­ply the al­co­hol so­lu­tion to the pump­kin and wait for the al­co­hol to evap­o­rate;

3. Turn on your black­light and en­joy the ef­fect: the whole pump­kin will glow!

This glow­ing pump­kin will look es­pe­cial­ly creepy and im­pres­sive un­der a black­light with the room lights off!

Why does the pump­kin glow? Many mark­ers con­tain dyes that glow in ul­tra­vi­o­let light. This in­ter­est­ing phe­nom­e­non is known as flu­o­res­cence.
