I am looking for food tricks, i.e. onion volcano for entertainment.?

Answer 1

I found this on the web for you...hope it helps. It looks like fun to try.

The concentric rings resulting from a sliced onion can be made into a model volcano for introducing topics on volcanology.

Materials: One large white onion, knife (electric knives make nice, even cuts), flat electric skillet, vegetable oil, ethyl alcohol (burner fuel), fireplace matches, goggles, and oven mits.

Safety Note: The liquids may not stay in the cone so be careful when lighting the vapors.

Procedure:
1. Preheat electric skillet. Put on the goggles.
2. Cut the onion in half. From one of the halves, cut a slice of onion approximately 1 to 1.5 cm thick.
3. Separate the rings.
4. Place the largest onion ring on the skillet. Stack the next largest ring on top of that and continue stacking until a cone with a hole in the top is made. The resulting structure should resemble a volcano.
5. Pour approximately 20 mL of vegetable oil into the volcano hole.
6. Pour approximately 10 mL of ethyl alcohol into the volcano hole.
7. Light a fireplace match and drop it into the volcano hole.
8. Turn off the room lights, and see flames shoot out of the top simulating an active volcano.

Extension: If you want orange flames, add NaCl to the alcohol or for red flames add LiCl to the alcohol.

I guess you wanna make this for Halloween, right? Try these out, they'll really freak out your firends.

Edible Spiders

These are very fragile, but enough stayed intact to give the desired effect...I used a decocrating tube to pipe the icing into spider shapes on waxed paper. They are made from Royal Icing, which needs to be used right away since it hardens to a rocklike texture very quickly!

Royal Icing
16 oz powdered sugar (icing sugar)
3 egg whites
1/2 tsp cream of tartar
Beat until peaks firmly hold their shape, and the more you beat it, the firmer it gets.


Eerie Eyeballs

Yields approximately 9 dozen bite-sized eyeballs

3 oz lemon gelatin (can be sugar-free)
1 cup hot water
1/2 cup miniature marshmallows
1 cup pineapple juice
8 oz cream cheese (can be lowfat/Neufchatel)
1 cup mayonnaise (can be fat-free)

Dissolve lemon gelatin in 1 cup water in double boiler, add marshmallows and stir to melt. Remove from heat. Add pineapple juice and cream cheese. Beat until well blended. Cool slightly. Fold in mayo. If you have a truffle candy mold or round ice cube trays, pour the mixture in the molds and leave to set in the fridge. Otherwise pour into a deep ceramic dish and chill until thickened or firm enough for scooping into eyeballs. Using a melonballer, scoop full balls of the mixture and set aside for decoration. To decorate, use liquid food coloring and an old detail paintbrush and get creative. You will need black food coloring for the pupils. Also, if you are in a hurry, instead of painting the colored irises, you can carefully dip the ball in a small pool of food coloring to approximate the iris, but still paint on the pupils.


Creepy Witches' Fingers

Yield: 5 dozen

1 cup Butter, softened
1 cup Icing sugar
1 Egg
1 tsp Almond extract
1 tsp Vanilla
2 2/3 cups Flour
1 tsp Baking powder
1 tsp Salt
3/4 cup Almonds, whole blanched
1 Tube red decorator gel
(optional)

Gross everyone out with these creepy cookies.
In bowl, beat together butter, sugar, egg, almond extract and vanilla. Beat in flour, baking soda, and salt. Cover and refrigerate 30 minutes. Working with one quarter of the dough at a time and keeping remainder refrigerated, roll heaping teaspoonful of dough into finger shape for each cookie. Press almond firmly into 1 end for nail. Squeeze in centre to create knuckle shape. Using paring knife, make slashes in several places to form knuckle.

Place on lightly greased baking sheets; bake in 325F (160C) oven for 20-25 minutes or until pale golden. Let cool for 3 minutes. Lift up almond, squeeze red decorator gel onto nail bed and press almond back in place, so gel oozes out from underneath. You can also make slashes in the finger and fill them with "blood."

Remove from baking sheets and let cool on racks. Repeat with remaining dough.


Brittle Meringue Bones

3 large egg whites
1/4 tsp. cream of tartar
1/8 tsp. salt

four 48 oz cans pineapple juice
one 96 oz bottle orange juice
four 2 liter bottles lemon-lime soda
one 1.75 liter bottle vodka
one 1.75 liter bottle rum

All measurements are approximate. Adjust to your own taste.
Mix well. Pour into your cauldron, preferably with chunks of dry ice to create the bubbling steam effect.
(Be careful NOT to drink or eat or in any way come in direct contact with skin with any chunks of dry ice -
you can get burned by the extreme cold!)


Penn & Teller's Bleeding Heart

INGREDIENTS

4 cups of water
four 3-oz. boxes or two 6-oz boxes of peach (pink; think of lung tissue)
or strawberry (redder; think of livers and hearts) gelatin dessert mix.
4 envelopes unflavored gelatin
one 12-ounce can unsweetened evaporated milk

1/2 cup grenadine syrup
1 cup light corn syrup
one small bottle (0.3 fl. oz.) red food coloring
3 drops blue food coloring
one 1-gallon food-storage bag (the plain kind without the zip closure)
6 1/2 cup heart-shaped gelatin mold or cake pan

PREPARATION

Boil the water. Put the packaged gelatin dessert and unflavored gelatin in a bowl and pour the boiling water over it, stirring constantly. Cool to room temperature (very important or the next step may present problems). Stir in the condensed milk. Note how it already is acquiring the color of freshly skinned flesh.

Pour the mixture into the gelatin mold. Cover the bottom of the mold (this will be the top when you serve it) with a layer about half an inch think. Refrigerate until it gels firmly.

Meanwhile, prepare a nice bladder of blood. Stir together the corn syrup, grenadine, and food colorings (we do it right in the measuring cup to save dish washing--every erg saved in preparation is an erg one can use to enjoy the Payoff). For the bladder (the bag that keeps the blood together inside the mass of gelatin) take the gallon-size food-storage bag and turn it inside out. Pour the blood mixture into one corner of the bag and twist it closed so that no air bubble is caught between the sauce and the twist. Tie a knot in the twisted plastic. Adjust the position of the knot so that when the bag lies on the counter, it's about 1 1/2 to 2 inches high, and tighten the knot. With a pair of scissors, snip off the frilly extra plastic outside the knot.

When the gelatin on the bottom of the mold is stiff and firm, position the bladder of blood in the mold, with the point of the bag just inside the point of the heart. Make sure there is at least 3/4" of space between all sides of the bag and the walls of the mold (this will ensure that your guests don't see clues ahead of time). Pour in the remaining gelatin until the mold is as full as you can handle. Don't worry if you see a little of the blood-bladder grazing the surface of the gelatin, as longs as it doesn't project too much; the side you are looking at now will be the bottom when you serve it.
Refrigerate until gelled firmly to the texture of fine, lean organ meat. It takes about 4 hours.

To unmold, put about 2 1/2 inches of hot, but not boiling water in your sink. Set your mold in the water so that the water comes just below the edge of the mold for 15 to 20 seconds; the time depends on the thickness of the mold pan. Remove the mold from the water, and run the blade of a knife around the edge of the gelatin. Invert your serving platter, ideally a white pedestal cake plate, on top and hold it firmly in place. Then use both hands to turn over the mold and the plate. Remove the mold; you may need to tap or shake the mold slightly to free the gelatin.

PRESENTATION

The blood looks prettiest when it flows over white plates, doilies, and table linen, which it may stain permanently--but what the hell, it's the effect that matters. To serve, use a nice, big Psycho-style chef's knife and stab the side of the gelatin about one third of the way up from the pointed end of the heart. Twist the knife slightly, and blood will start to ooze out. Bare your teeth like a Marine jabbing with bayonet, and widen the wound. When the blood is coming at a good slip, grab a dessert plate, and cut a slice from one of the lobes of the heart. Flip it onto the plate, and drizzle it with blood by holding it under the edge of the pedestal. Add whipped cream and serve.

This dish delights all five senses:

1. Sight: red, glossy, and elegantly surreal when the blood starts to flow.
2. Taste: sweeeet.
3. Smell: classic artificial-fruity
4. Touch: cold and wiggly.
5. Hearing: the screaming of guests.

A NOTE ABOUT SAFETY: Be careful not to serve pieces of the food-storage bag to your friends. They could choke to death. We want to help you become a more exciting host, not a criminally negligent klutz.

Here's wishing you a very HAPPY HALLOWEEN!
